treatment | What are the treatments for Sialadenitis ? | How might sialadenitis be treated? The initial treatment for sialadenitis is antibiotics active against S. aureus. Hydration, ingesting things that trigger saliva flow (such as lemon juice or hard candy), warm compresses, gland massage, and good oral hygiene are also important. Abscesses need to be drained. Occasionally, in cases of chronic or relapsing sialadenitis, a superficial parotidectomy or submandibular gland excision is needed. |
information | What is (are) Cherubism ? | Cherubism is a rare disorder characterized by abnormal bone tissue in the lower part of the face. The enlarged bone is replaced with painless, cyst-like growths that give the cheeks a swollen, rounded appearance and frequently interfere with normal tooth development. The condition may be mild or severe. People with the severe form may have problems with vision, breathing, speech, and swallowing. Many adults with cherubism have a normal facial appearance. Most people with cherubism do not any other signs and symptoms. The condition is inherited in an autosomal dominant fashion and is caused by mutations in the SH3BP2 gene., in most cases. |
symptoms | What are the symptoms of Cherubism ? | What are the signs and symptoms of Cherubism? Cherubism is characterized by abnormal bone tissue in the lower part of the face. Beginning in early childhood, both the lower jaw (the mandible) and the upper jaw (the maxilla) become enlarged as bone is replaced with painless, cyst-like growths. These growths give the cheeks a swollen, rounded appearance and often interfere with normal tooth development. In some people the condition is very mild and barely noticeable, while in other cases are severe enough to cause problems with vision, breathing, speech, and swallowing. Enlargement of the jaw usually continues throughout childhood and stabilizes during puberty. The abnormal growths are gradually replaced with normal bone in early adulthood. As a result, many affected adults have a normal facial appearance. The Human Phenotype Ontology provides the following list of signs and symptoms for Cherubism. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms. Signs and Symptoms Approximate number of patients (when available) Abnormality of the mandible 90% Neoplasm of the skeletal system 90% Abnormality of dental morphology 50% Reduced number of teeth 50% Abnormality of the voice 7.5% Apnea 7.5% Feeding difficulties in infancy 7.5% Optic atrophy 7.5% Proptosis 7.5% Visual impairment 7.5% Autosomal dominant inheritance - Childhood onset - Constriction of peripheral visual field - Macular scarring - Marcus Gunn pupil - Oligodontia - Optic neuropathy - Reduced visual acuity - Round face - Striae distensae - The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common. |
causes | What causes Cherubism ? | How does one get cherubism? What causes cherubism? Genetic changes (mutations) in the SH3BP2 gene cause cherubism. About 80 percent of people with cherubism have a mutation in the SH3BP2 gene. In most of the remaining cases, the genetic cause of the condition is unknown. |
inheritance | Is Cherubism inherited ? | If I find that I am not a carrier for cherubism can I still have children with the disease? Yes. Again, only 80 percent of people with cherubism have an identifiable mutation in the SH3BP2 gene. In the remaining cases, the cause is genetic, but unknown. Individuals who do not have an identifiable genetic cause can still have children with cherubism. |
information | What is (are) Reactive arthritis ? | Reactive arthritis is a type of infectious arthritis that occurs as a reaction to an infection elsewhere in the body. This process may occur weeks or even months after the infection has resolved. In addition to joint inflammation, reactive arthritis is associated with two other symptoms: redness and inflammation of the eyes (conjunctivitis) and inflammation of the urinary tract (urethritis). These symptoms may occur alone, together, or not at all. The symptoms of reactive arthritis usually last 3 to 12 months, although symptoms can return or develop into a long-term disease in a small percentage of people. The exact cause of reactive arthritis is unknown. It may follow an infection with Salmonella enteritidis, Salmonella typhimurium, Yersinia enterocolitica, Campylobacter jejuni, Clostridium difficile, Shigella sonnei, Entamoeba histolytica, Cryptosporidium, or Chlamydia trachomatis. Certain genes may make you more prone to the syndrome. For instance, the condition is observed more commonly in patients with human lymphocyte antigen B27 (HLA-B27) histocompatibility antigens. The goal of treatment is to relieve symptoms and treat any underlying infection. Antibiotics may be prescribed. Nonsteroidal anti-inflammatory drugs (NSAIDS), pain relievers, and corticosteroids may be recommended for those with joint pain. |

information | What is (are) Hydrocephalus due to congenital stenosis of aqueduct of sylvius ? | Hydrocephalus due to congenital stenosis of aqueduct of sylvius (HSAS) is a form of L1 syndrome, which is an inherited disorder that primarily affects the nervous system. Males with HSAS are typically born with severe hydrocephalus and adducted thumbs (bent towards the palm). Other sign and symptoms of the condition include severe intellectual disability and spasticity. HSAS, like all forms of L1 syndrome, is caused by changes (mutations) in the L1CAM gene and is inherited in an X-linked recessive manner. Treatment is based on the signs and symptoms present in each person. |

inheritance | Is Hydrocephalus due to congenital stenosis of aqueduct of sylvius inherited ? | Is hydrocephalus due to congenital stenosis of aqueduct of sylvius inherited? Hydrocephalus due to congenital stenosis of aqueduct of sylvius is inherited in an X-linked recessive manner. A condition is X-linked if the responsible gene is located on the X chromosome. The X chromosome is one of the two sex chromosomes (the other sex chromosome is the Y chromosome). Females have two X chromosomes in each cell and males have an X chromosome and a Y chromosome in each cell. Although females have two X chromosomes, one of the X chromosomes in each cell is "turned off" and all of the genes on that chromosome are inactivated. Females who have a change (mutation) in a gene on one of their X chromosomes are called carriers of the related condition. Carrier females usually do not have symptoms of the condition because the X chromosome with the mutated gene is often turned off and they have another X chromosome with a working copy of the gene. Sometimes, the X chromosome with the working copy of the gene is turned off, which may cause symptoms of the condition. However, females with symptoms are usually much more mildly affected than males. A male has only one X chromosome, so if he inherits a mutation on the X chromosome, he will have signs and symptoms (be affected). Males with an X-linked recessive condition always pass the mutated gene to all of their daughters, who will be carriers. A male cannot pass an X-linked gene to his sons because males always pass their Y chromosome to male offspring. Female carriers of an X-linked recessive condition have a 25% chance with each pregnancy to have a carrier daughter like themselves, a 25% chance to have a non-carrier daughter, a 25% chance to have an affected son, and a 25% chance to have an unaffected son. This also means that each daughter of a carrier mother has a 50% chance of being a carrier, and each son has a 50% chance of having the condition. |
exams and tests | How to diagnose Hydrocephalus due to congenital stenosis of aqueduct of sylvius ? | How is hydrocephalus due to congenital stenosis of aqueduct of sylvius diagnosed? A diagnosis of hydrocephalus due to congenital stenosis of aqueduct of sylvius is typically suspected based on the presence of characteristic signs and symptoms on physical examination and/or brain imaging (i.e. CT scan, MRI scan). Identification of a change (mutation) in the L1CAM gene can be used to confirm the diagnosis. |
treatment | What are the treatments for Hydrocephalus due to congenital stenosis of aqueduct of sylvius ? | How might hydrocephalus due to congenital stenosis of aqueduct of sylvius be treated? The treatment of hydrocephalus due to congenital stenosis of aqueduct of sylvius (HSAS) is based on the signs and symptoms present in each person. For example, hydrocephalus is typically treated with shunt surgery. Special education and early intervention may be recommended for children with intellectual disability. Although intervention is rarely necessary for adducted thumbs (bent towards the palms), tendon transfer surgery or splinting may be suggested in some cases. |

treatment | What are the treatments for Fanconi Bickel syndrome ? | How might Fanconi Bickel syndrome be treated? Management of Fanconi Bickel syndrome (FBS) generally focuses on the signs and symptoms of the condition. Treatment includes replacement of water and electrolytes, and vitamin D and phosphate supplements for prevention of hypophosphatemic rickets. Although there is limited data on the effectiveness of dietary treatment for this condition, it is recommended that affected individuals follow a galactose-restricted diabetic diet, with fructose as the main source of carbohydrate. Diet and supplements may alleviate some of the signs and symptoms of the condition but generally do not improve growth, resulting in short stature in adulthood. |
information | What is (are) Down syndrome ? | Down syndrome is a chromosome disorder associated with intellectual disability, a characteristic facial appearance, and low muscle tone in infancy. The degree of intellectual disability varies from mild to moderate. People with Down syndrome may also be born with various health concerns such as heart defects or digestive abnormalities. They also have an increased risk to develop gastroesophageal reflux, celiac disease, hypothyroidism, hearing and vision problems, leukemia, and Alzheimer disease. Down syndrome is caused by having three copies of chromosome 21 (called trisomy 21) instead of the usual two copies and is typically not inherited. Treatment focuses on the specific symptoms in each person. |
symptoms | What are the symptoms of Down syndrome ? | What are the signs and symptoms of Down syndrome? People with Down syndrome may develop the following medical problems: Congenital hypothyroidism Hearing loss Congenital heart defects Seizures Vision disorders Decreased muscle tone (hypotonia) Children with Down syndrome are also more likely to develop chronic respiratory infections, middle ear infections, and recurrent tonsillitis. In addition, there is a higher incidence of pneumonia in children with Down syndrome than in the general population. Children with Down syndrome have developmental delay. They are often slow to turn over, sit, and stand. Developmental delay may be related to the child's weak muscle tone. Development of speech and language may also take longer than expected. Children with Down syndrome may take longer than other children to reach their developmental milestones, but many of these milestones will eventually be met. Adults with Down syndrome have an increased risk of developing Alzheimer disease, a brain disorder that results in a gradual loss of memory, judgment, and ability to function. Although Alzheimer disease is usually a disorder that occurs in older adults, about half of adults with Down syndrome develop this condition by age 50. The Human Phenotype Ontology provides the following list of signs and symptoms for Down syndrome.

causes | What causes Down syndrome ? | What causes Down syndrome? There are 3 possible genetic causes of Down syndrome: Trisomy 21. Most often, Down syndrome is caused by an extra chromosome 21 in all cells of the affected person. In these cases, the chromosome 21 pair fails to separate during the formation of an egg (or sperm); this is called "nondisjunction." When the egg with 2 copies of chromosome 21 unites with a normal sperm with one copy of chromosome 21 to form an embryo, the resulting embryo has 3 copies of chromosome 21 instead of the normal two. The extra chromosome is then copied in every cell of the baby's body, causing the features of Down syndrome. The cause of nondisjunction is unknown, but research has shown that it happens more often as women age. Nondisjunction is not known to be caused by anything in the environment or anything that parents do (or don't do) before or during pregnancy. Mosaic trisomy 21. In about 1-2% of cases, only some of the cells in a person's body have an extra chromosome 21; this is called "mosaic trisomy 21". In this situation, the fertilized egg may have the right number of chromosomes, but due to a cell division error early in the development of the embryo, some cells "acquire" an extra chromosome 21. A person with mosaic trisomy 21 typically has 46 chromosomes in some cells, and 47 chromosomes (with the extra chromosome 21) in others. The features and severity in people with mosaic trisomy 21 may vary widely. Translocation trisomy 21. About 3-4% of people with Down syndrome have cells that contain 46 chromosomes; however, there is extra chromosome 21 material attached (translocated ) onto another chromosome. For parents of a child with Down syndrome due to a translocation, there may be an increased chance of Down syndrome in future pregnancies. This is because one of the two parents may be a carrier of a balanced translocation. However, not all parents of people with translocation trisomy 21 have a translocation. Regardless of the type of Down syndrome a person has, all people with Down syndrome have an extra, critical portion of chromosome 21 present in all or some of their cells. This extra genetic material disrupts the normal course of development, causing the characteristic features of Down syndrome. |
exams and tests | How to diagnose Down syndrome ? | How is Down syndrome diagnosed? Down syndrome may be suspected and/or diagnosed during pregnancy, or after a child is born. During pregnancy, a woman can opt to have specific tests that may either screen for, or diagnosis, Down syndrome in a fetus. A screening test poses no risks to the fetus and can determine the likelihood that a fetus has Down syndrome. It may show that a fetus is at an increased risk to be affected, but cannot determine whether it is definitely affected. Screening tests for Down syndrome may involve different types of blood tests for the mother and/or specific types of ultrasounds that can detect features more common in fetuses with Down syndrome (called markers). Depending on the type of screening tests a woman has, they may be done during the 1st trimester, the 2nd trimester, or both. If a screening test shows an increased risk for Down syndrome, a woman may then choose to have a diagnostic test. Diagnostic tests during pregnancy can determine with certainty whether a fetus has Down syndrome, but they are invasive and carry a slight risk of miscarriage. Examples of diagnostic tests include chorionic villus sampling in the 1st trimester and amniocentesis in the 2nd trimester. During these tests, a small sample of genetic material is obtained from the amniotic fluid or placenta, and the fetus' chromosomes are then analyzed in a laboratory. In recent years, non-invasive prenatal testing (NIPT) has become available to women who are at increased risk to have a baby with Down syndrome. NIPT is a blood test that examines DNA from the fetus in the mother's bloodstream. However, women who have a positive NIPT result should then have invasive diagnostic testing to confirm the result. People with questions about the different options for prenatal screening or diagnostic testing should speak with a genetic counselor. A genetic counselor can discuss the benefits, limitations and risks of each test, and help each person decide which test (if any) is best for them. If a diagnosis of Down syndrome is not made prenatally, the diagnosis can be made in the newborn. Down syndrome may be suspected if a newborn has characteristic physical features of the condition. The diagnosis can then be confirmed by obtaining a karyotype (a blood test to look at a picture of the newborn's chromosomes). |
treatment | What are the treatments for Down syndrome ? | How might Down syndrome be treated? Early intervention services, quality educational programs, a stimulating home environment, good health care, and positive support from family and friends can help people with Down syndrome develop to their full potential. The overall goal of treatment is to boost cognition by improving learning, memory, and speech. Other treatments depend on the specific health problems or complications present in each affected person. The Research Down syndrome Foundation have a webpage with information about active reseach projects. |

information | What is (are) Churg Strauss syndrome ? | Churg Strauss syndrome is a condition characterized by asthma, high levels of eosinophils (a type of white blood cell that helps fight infection), and inflammation of small to medium sized blood vessels (vasculitis). The inflamed vessels can affect various organ systems including the lungs, gastrointestinal tract, skin, heart and nervous system. The exact cause of Churg Strauss syndrome is unknown, but it is thought to be an autoimmune disorder. Treatment may involve the use of glucocorticoids and/or other immunosuppressive therapies. |
symptoms | What are the symptoms of Churg Strauss syndrome ? | What are the signs and symptoms of Churg Strauss syndrome? The specific signs and symptoms of Churg Strauss syndrome (CSS) vary from person to person depending on the organ systems involved. The severity, duration and age of onset also vary. CSS is considered to have three distinct phases - prodromal (allergic), eosinophilic and vasculitic - which don't always occur sequentially. Some people do not develop all three phases. The prodromal (or allergic) phase is characterized by various allergic reactions. Affected people may develop asthma (including a cough, wheezing, and shortness of breath); hay fever (allergic rhinitis); and/or repeated episodes of sinusitis. This phase can last from months to many years. Most people develop asthma-like symptoms before any other symptoms. The eosinophilic phase is characterized by accumulation of eosinophils (a specific type of white blood cell) in various tissues of the body - especially the lungs, gastrointestinal tract and skin. The vasculitic phase is characterized by widespread inflammation of various blood vessels (vasculitis). Chronic vasculitis can cause narrowing of blood vessels, which can block or slow blood flow to organs. Inflamed blood vessels can also become thin and fragile (potentially rupturing) or develop a bulge (aneurysm). People with CSS often develop nonspecific symptoms including fatigue, fever, weight loss, night sweats, abdominal pain, and/or joint and muscle pain. Neurological symptoms (such as pain, tingling or numbness) are common and depend on the specific nerves involved. About half of affected people develop skin abnormalities due to accumulation of eosinophils in skin tissue. Symptoms of skin involvement may include purplish skin lesions, a rash with hives, and/or small bumps, especially on the elbows. Gastrointestinal involvement may cause various symptoms also. Heart problems may include inflammation of heart tissues and in severe cases, heart failure. The kidneys can also become involved, eventually causing glomerulonephritis.

information | What is (are) Lennox-Gastaut syndrome ? | Lennox-Gastaut syndrome is a form of severe epilepsy that begins in childhood. It is characterized by multiple types of seizures and intellectual disability. This condition can be caused by brain malformations, perinatal asphyxia (lack of oxygen), severe head injury, central nervous system infection and inherited degenerative or metabolic conditions. In about one-third of cases, no cause can be found. Treatment for Lennox-Gastaut syndrome includes anti-epileptic medications such as valproate, lamotrigine, felbamate, or topiramate. There is usually no single antiepileptic medication that will control seizures. Children may improve initially, but many later show tolerance to a drug or develop uncontrollable seizures. |

causes | What causes Gerstmann-Straussler-Scheinker disease ? | What causes Gerstmann-Straussler-Scheinker disease? Gerstmann-Straussler-Scheinker disease (GSS) is usually caused by certain changes (mutations) in the PRNP gene. PRNP encodes a protein called prion protein. Although the exact function of this protein is unknown, it appears to play an important role in the human brain and other tissues throughout the body. People affected by GSS generally have mutations in the PRNP gene that result in the production of an abnormally shaped prion protein. The abnormal protein builds up in the brain, forming clumps that damage or destroy neurons. This loss of brain cells leads to the signs and symptoms of GSS. |
inheritance | Is Gerstmann-Straussler-Scheinker disease inherited ? | How is Gerstmann-Straussler-Scheinker disease inherited? Gerstmann-Straussler-Scheinker disease (GSS) is inherited in an autosomal dominant manner. This means that to be affected, a person only needs a change (mutation) in one copy of the responsible gene in each cell. In some cases, an affected person inherits the mutation from an affected parent. Other cases may result from new (de novo) mutations in the gene. These cases occur in people with no history of the disorder in their family. A person with GSS has a 50% chance with each pregnancy of passing along the altered gene to his or her child. |
exams and tests | How to diagnose Gerstmann-Straussler-Scheinker disease ? | How is Gerstmann-Straussler-Scheinker disease diagnosed? The diagnosis of Gerstmann-Straussler-Scheinker disease (GSS) is based on a combination of the following: Characteristic signs and symptoms Nervous system findings including multiple amyloid plaques (clumps which form in the brain and cause the death of nerve cells and the progressive symptoms of the disease) A family history consistent with autosomal dominant inheritance Identification of a disease-causing mutation of the PRNP gene Genetic testing for at-risk relatives who do not yet have symptoms of GSS is possible if the disease-causing mutation in the family is known. This testing is not useful in predicting age of onset, severity, type of symptoms, or rate of progression. Testing for the disease-causing mutation in the absence of definite symptoms of the disease is called predictive testing. |
treatment | What are the treatments for Gerstmann-Straussler-Scheinker disease ? | How might Gerstmann-Straussler-Scheinker disease be treated? The treatment of Gerstmann-Straussler-Scheinker disease (GSS) is based on the signs and symptoms present in each person. There is currently no cure for the condition and no known treatments to slow its progression. GeneReviews' Web site offers more specific information about the treatment and management of GSS and other genetic prion diseases. Please click on the link to access this resource. |
information | What is (are) Hereditary cerebral hemorrhage with amyloidosis ? | Cerebral amyloid angiopathy (CAA) is a neurological condition in which amyloid protein is deposited onto the walls of the arteries of the brain (and less frequently, veins). Although CAA often does not cause symptoms, it may cause bleeding into the brain (hemorrhagic stroke), dementia, or neurologic episodes in some patients. The majority of CAA cases occur in individuals who do not have a family history. However, two familial forms of CAA have been identified. |
symptoms | What are the symptoms of Hereditary cerebral hemorrhage with amyloidosis ? | What symptoms may be associated with hereditary cerebral hemorrhage with amyloidosis - Dutch type? Approximately 87% of individuals with hereditary cerebral hemorrhage with amyloidosis - Dutch type have intracranial hemorrhage (bleeding in the brain) and 13% have infarcts (stroke). The first stroke usually occurs between the ages of 45 and 65 years, and is not caused by hypertension or hemorrhagic diathesis (bleeding tendency). Nausea, vomiting, progressive headache, focal neurological signs (double or decreased vision, speech difficulties, confusion, delirium, weakness or paralysis, sensation changes or loss of sensation, progressive intellectual deterioration and memory disturbance) and impairment of consciousness are the most frequent signs and symptoms. Psychiatric abnormalities, including dementia are also common, with some patients developing dementia without intracranial hemorrhage. |
causes | What causes Hereditary cerebral hemorrhage with amyloidosis ? | What causes hereditary cerebral hemorrhage with amyloidosis - Dutch type? The clinical symptoms of hereditary cerebral hemorrhage with amyloidosis - Dutch type are caused by the build-up of a protein called amyloid within the arterial walls of the brain. This protein build-up causes bleeding into the brain. The symptoms occur because bleeding in the brain harms brain tissue. Hereditary cerebral hemorrhage with amyloidosis-Dutch type is an autosomal dominant disorder with complete penetrance (all individuals who inherit the mutated gene will develop the condition). The likely genetic defect is in the amyloid protein precursor protein (APP) gene on chromosome 21. |
inheritance | Is Hereditary cerebral hemorrhage with amyloidosis inherited ? | Since I have a family history of hereditary cerebral hemorrhage with amyloidosis, what are the chances that I inherited the condition? To find out your chances of having hereditary cerebral hemorrhage with amyloidosis, you may want to speak with a genetics professional. A genetics professionl can review your medical and family history in order to provide you with your specific risks. To learn more about genetic consultations, click here. |
treatment | What are the treatments for Hereditary cerebral hemorrhage with amyloidosis ? | How might hereditary cerebral hemorrhage with amyloidosis - Dutch type be treated? There is no known effective treatment for hereditary cerebral hemorrhage with amyloidosis - Dutch type. Treatment is supportive and based on the control of symptoms. In some cases, rehabilitation is needed for weakness or clumsiness. This can include physical, occupational, or speech therapy. Occasionally, some patients are good candidates for medications that can help improve memory. The management of intracranial hemorrhage (ICH) related to hereditary cerebral hemorrhage with amyloidosis - Dutch type is identical to the standard management of ICH. The main objectives include reversing anticoagulation, managing intracranial pressure, and preventing complications. |
information | What is (are) Fragile X syndrome ? | Fragile X syndrome is a genetic condition involving changes in part of the X chromosome. This condition causes a range of developmental problems including learning disabilities and cognitive impairment. It is the most common form of inherited intellectual disability in males and a significant cause of intellectual disability in females. Other signs and symptoms may include symptoms of autism spectrum disorders, seizures, and characteristic physical features. Fragile X syndrome is caused by a change (mutation) in the FMR1 gene and is inherited in an X-linked dominant manner. |
symptoms | What are the symptoms of Fragile X syndrome ? | What are the signs and symptoms of Fragile X syndrome? Fragile X syndrome is characterized by developmental problems including intellectual disability and delayed speech and language development. Males are usually more severely affected than females. Additional features may include anxiety; attention deficit disorder (ADD); features of autism spectrum disorders that affect communication and social interaction; and seizures. Most males and some females with fragile X syndrome have characteristic physical features that become more apparent with age. These features may include a long and narrow face; large ears; a prominent jaw and forehead; unusually flexible fingers; flat feet; and in males, enlarged testicles (macroorchidism) after puberty. The Human Phenotype Ontology provides the following list of signs and symptoms for Fragile X syndrome.

In these cases, the sign or symptom may be rare or common. |
causes | What causes Fragile X syndrome ? | What causes fragile X syndrome? Mutations (changes) in the FMR1 gene cause fragile X syndrome (FXS). This gene carries instructions to make a protein called the fragile X mental retardation 1 protein. The FMR1 gene contains a section of DNA called a CGG triplet repeat, which normally repeats from 5 to around 40 times. In most cases of FXS, this section of DNA is repeated more than 200 times, which "turns off" the FMR1 gene and disrupts the function of the nervous system. In a small portion of cases, other types of changes in the FMR1 gene cause FXS. These changes may involve a deletion of all or part of the gene, or a change in the building blocks (amino acids) used to make the gene's protein. People with 55 to 200 repeats of the CGG segment are said to have an FMR1 premutation. Most people with a premutation are intellectually normal. In some cases, people with a premutation have lower levels of the gene's protein and may have some mild symptoms of FXS. About 20% of women with a premutation have premature ovarian failure, and some people with a premutation have an increased risk of developing fragile X-associated tremor/ataxia syndrome (FXTAS). |
inheritance | Is Fragile X syndrome inherited ? | How is fragile X syndrome inherited? Fragile X syndrome (FXS) is inherited in an X-linked dominant manner. A condition is X-linked if the responsible gene is located on the X chromosome. The inheritance is dominant if having only one changed (mutated) copy of the responsible gene is enough to cause symptoms of the condition. In women who carry an FMR1 gene premutation (approximately 55 to 200 CGG repeats), the repeats can expand to more than 200 repeats in their cells that develop into eggs. This means that women with a premutation (or a full mutation) have an increased risk to have a child with FXS. The size of the risk corresponds to the number of CGG repeats they have. By contrast, men with premutations are not at risk for the repeats expanding to over 200 when passing the gene to offspring. However, men with a premutation will pass the premutation on to all of their daughters and none of their sons. This is because boys receive only a Y chromosome from their fathers. |
exams and tests | How to diagnose Fragile X syndrome ? | Is genetic testing available for fragile X syndrome? Yes, genetic testing is available for fragile X syndrome. Carrier testing for at-risk relatives and prenatal testing for pregnancies at increased risk are possible if the diagnosis of an FMR1-related disorder (including fragile X syndrome) has been confirmed in a family member. The Genetic Testing Registry (GTR) provides information about the labs that offer genetic testing for fragile X syndrome. The intended audience for the GTR is health care providers and researchers. People with questions about genetic testing should speak with a health care provider or genetics professional. |
treatment | What are the treatments for Fragile X syndrome ? | How might fragile X syndrome be treated? There is no specific treatment available for fragile X syndrome. Management of this condition is generally supportive and may include: recognizing the need for special education and avoiding excessive stimulation, which may help with behavioral problems early educational intervention and special education that is tailored to specific learning difficulties; small class size, individual attention and avoidance of sudden change is often needed medications for behavioral issues that affect social interaction routine medical management of strabismus, ear infections, reflux, seizures, mitral valve prolapse, and/or high blood pressure. |

information | What is (are) Syndactyly type 3 ? | Syndactyly type 3 (SD3) is a limb abnormality present at birth that is characterized by complete fusion of the 4th and 5th fingers on both hands. In most cases only the soft tissue is fused, but in some cases the bones of the fingers (distal phalanges) are fused. There is evidence that SD3 is caused by mutations in the GJA1 gene, which has also been implicated in a condition called oculodentodigital dysplasia. SD3 is the characteristic digital abnormality in this condition. SD3 is inherited in an autosomal dominant manner. |

inheritance | Is Syndactyly type 3 inherited ? | How is syndactyly type 3 inherited? Syndactyly type 3 has been shown to be inherited in an autosomal dominant manner. This means that having only one mutated copy of the causative gene is sufficient to cause the condition. When an individual with an autosomal dominant condition has children, each child has a 50% (1 in 2) chance of inheriting the mutated gene and a 50% chance of inheriting the normal gene and being unaffected. |
information | What is (are) Opitz G/BBB syndrome ? | Opitz G/BBB syndrome is an inherited condition that affects several structures along the midline of the body. The most common features are wide-spaced eyes and defects of the larynx, trachea, and/or esophagus causing breathing problems and difficulty swallowing. Affected males usually have a urethra opening on the underside of the penis (hypospadias). Other features can include mild intellectual disability, cleft lip and/or a cleft palate, heart defects, an obstruction of the anal opening (imperforate anus), agenesis of the corpus callosum, and facial abnormalities. These features may vary, even among members of the same family. There are two forms of Opitz G/BBB syndrome, which are distinguished by their genetic causes and patterns of inheritance. The X-linked form is caused by mutations in the MID1 gene. Autosomal dominant Opitz G/BBB syndrome is caused by a deletion of 22q11.2, and is often referred to as 22q11.2 deletion syndrome. Treatment depends on the individuals specific needs. |
symptoms | What are the symptoms of Opitz G/BBB syndrome ? | What are the signs and symptoms of Opitz G/BBB syndrome? Opitz G/BBB syndrome mainly affects structures along the midline of the body. The most common features of the condition are wide-spaced eyes (hypertelorism); defects of the larynx, trachea, and/or esophagus causing breathing problems and difficulty swallowing (dysphagia); and in males, the urethra opening on the underside of the penis (hypospadias). Mild intellectual disability and developmental delay occur in about 50 percent of people with Opitz G/BBB syndrome. Delays in motor skills, speech delays, and learning difficulties may also occur. Some individuals with Opitz G/BBB syndrome have features similar to autistic spectrum disorders, including impaired communication and socialization skills. About half of affected individuals also have cleft lip with or without a cleft palate. Some have cleft palate alone. Heart defects, an obstruction of the anal opening (imperforate anus), and brain defects such as an absence of the tissue connecting the left and right halves of the brain (agenesis of the corpus callosum) occur in less than 50 percent of those affected. Facial abnormalities that may be seen in this disorder can include a flat nasal bridge, thin upper lip, and low set ears. These features vary among affected individuals, even within the same family. The signs and symptoms of the autosomal dominant form of the condition are comparable to those seen in the X-linked form. However, the X-linked form of Opitz G/BBB syndrome tends to include cleft lip with or without cleft palate, while cleft palate alone is more common in the autosomal dominant form. Females with X-linked Opitz G/BBB syndrome are usually mildly affected, as hypertelorism may be the only sign of the disorder. The Human Phenotype Ontology provides the following list of signs and symptoms for Opitz G/BBB syndrome.

causes | What causes Opitz G/BBB syndrome ? | What causes Opitz G/BBB syndrome? The X-linked form of Opitz G/BBB syndrome is caused by mutations in the MID1 gene. The MID1 gene provides instructions for making a specific protein called midline-1. This protein helps regulate the function of microtubules, which are rigid, hollow fibers that make up the cell's structural framework (the cytoskeleton). Microtubules help cells maintain their shape, assist in the process of cell division, and are essential for the movement of cells (cell migration). The MID1 gene is a member of a group of genes called the TRIM (tripartite motif) family. The proteins produced from this large family of genes are involved in many cellular activities. Primarily, TRIM proteins play a role in the cell machinery that breaks down (degrades) unwanted proteins. As part of its protein degrading function, midline-1 is responsible for recycling certain proteins, including phosphatase 2A (PP2A), integrin alpha-4 (ITGA4), and serine/threonine-protein kinase 36 (STK36). The recycling of these three proteins so they can be reused instead of broken down is essential because they are needed for normal cellular functioning. Mutations in the MID1 gene lead to a decrease in midline-1 function, which prevents this protein recycling. As a result, certain proteins are not recycled, and they accumulate in cells. This buildup impairs microtubule function, resulting in problems with cell division and migration. Researchers speculate that the altered midline-1 protein affects how the cells divide and migrate along the midline of the body during development, resulting in the features of Opitz G/BBB syndrome. Some people who have a family history of X-linked Opitz G/BBB syndrome have no detectable MID1 mutation. The reason for this is not yet known, although some researchers have suggested the involvement of other unknown genes. The autosomal dominant form of Opitz G/BBB syndrome is caused by a deletion of a small piece of chromosome 22, specifically 22q11.2, which is why researchers consider this condition to be part of 22q11.2 deletion syndrome. It is not yet known which deleted gene(s) within this region of chromosome 22 specifically cause the signs and symptoms of Opitz G/BBB syndrome. In others with autosomal dominant Opitz G/BBB syndrome, the cause is related to a mutation in the SPECCIL gene. Click on the gene name to learn more about its role in the development of this condition. |
inheritance | Is Opitz G/BBB syndrome inherited ? | How is Opitz G/BBB syndrome inherited? Opitz G/BBB syndrome often has an X-linked pattern of inheritance. A condition is considered X-linked if the mutated gene that causes the disorder is located on the X chromosome, one of the two sex chromosomes (the other sex chromosome is the Y chromosome). In most cases, males experience more severe symptoms of the disorder than females. This is because females have two different X chromosomes in each cell, and males have one X chromosome and one Y chromosome. A characteristic of X-linked inheritance is that fathers cannot pass X-linked traits to their sons, because fathers only pass a Y chromosome on to their sons (which is what makes them male). In some cases, an affected person inherits a MID1 mutation from an affected parent, while in other cases, it may result from a new mutation in the affected individual. These cases occur in people with no history of the disorder in their family. A female who has the X-linked form of Opitz G/BBB syndrome has a 25% (1 in 4) chance to have a daughter with the mutation, a 25% chance to have a son with the mutation, a 25% chance to have an unaffected daughter, and a 25% chance to have an unaffected son. This also means that there is a 50% chance, with each pregnancy, for the child to inherit the mutation. A male with the X-linked dominant form of Opitz G/BBB syndrome will pass the mutation on to all of his daughters and none of his sons. Researchers have also described an autosomal dominant form of Opitz G/BBB syndrome caused by a deletion in one copy of chromosome 22 in each cell. In some cases, an affected person inherits the chromosome with a deleted segment from a parent, while in other cases, the condition results from a new deletion in the affected individual. These cases occur in people with no history of the disorder in their family. Males and females with the autosomal dominant form of Opitz G/BBB syndrome usually have the same degree of severity of symptoms. A male or female who has the autosomal dominant form of Opitz G/BBB syndrome has a 50% (1 in 2) chance with each pregnancy for the child (male or female) to inherit the genetic abnormality. |
exams and tests | How to diagnose Opitz G/BBB syndrome ? | How is Opitz G/BBB syndrome diagnosed? The diagnosis of Opitz G/BBB syndrome is usually based on clinical findings. In order to differentiate the X-linked form from 22q11.2 deletion syndrome (the autosomal dominant form), the pattern of inheritance within the family may be assessed. Molecular genetic testing for mutations in the MID1 gene is available for confirmation. Between 15 and 45% of males with clinically diagnosed Opitz G/BBB syndrome are found to have a mutation in this gene. |
treatment | What are the treatments for Opitz G/BBB syndrome ? | How might Opitz G/BBB syndrome be treated? Because of the wide range of signs and symptoms that may be present in affected individuals, management of Opitz G/BBB syndrome typically incorporates a multidisciplinary team consisting of various specialists. Treatment for the condition may include surgery for significant abnormalities involving the larynx, trachea and/or esophagus; surgical intervention as needed for hypospadias, cleft lip and/or cleft palate, and imperforate anus; therapy for speech problems; surgical repair as needed for heart defects; neuropsychological support; and special education services. |
information | What is (are) Rickets ? | Rickets is a condition that causes children to have soft, weak bones. It usually occurs when children do not get enough vitamin D, which helps growing bones absorb important nutrients. Vitamin D comes from sunlight and food. Skin produces vitamin D in response to the sun's rays. Some foods also contain vitamin D, including fortified dairy products and cereals, and some kinds of fish. |
symptoms | What are the symptoms of Rickets ? | What are the signs and symptoms of rickets? The signs and symptoms of rickets include: Bone pain or tenderness Bowed (curved) legs Large forehead Stunted growth Abnormally curved spine Large abdomen Abnormally shaped ribs and breastbone Wide wrist and elbow joints Teeth abnormalities |
causes | What causes Rickets ? | What causes rickets? Rickets is caused by a lack of vitamin D. A child might not get enough vitamin D if he or she: Has dark skin Spends too little time outside Has on sunscreen all the time when out of doors Doesn't eat foods containing vitamin D because of lactose intolerance or a strict vegetarian diet Is breastfed without receiving vitamin D supplements Can't make or use vitamin D because of a medical disorder such as celiac disease Has an inherited disorder that affects vitamin D levels |
exams and tests | How to diagnose Rickets ? | How is rickets diagnosed? Rickets is typically diagnosed using specific blood tests and x-rays. Blood tests usually show low levels of calcium and phosphorus and high levels of alkaline phosphatase. Bone x-rays may show areas with calcium loss or changes in bone shape. Bone biopsies are rarely performed, but can confirm the diagnosis of rickets. |
treatment | What are the treatments for Rickets ? | What treatment is available for rickets? The treatment for rickets depends on the cause of the condition. If rickets is caused by a lack of vitamin D in the diet, then it is usually treated with carefully adjusted levels of vitamin D and calcium. The child's condition may improve within a few weeks of treatment. If rickets is caused by an inherited disorder or another medical condition, a healthcare provider would determine the appropriate treatment. |
information | What is (are) Variant Creutzfeldt-Jakob disease ? | There are several known variants of Creutzfeldt-Jakob disease (CJD). These variants differ somewhat in the symptoms and course of the disease. For example, a variant form of the disease-called new variant or variant (nv-CJD, v-CJD), described in Great Britain and France, begins primarily with psychiatric symptoms, and has a longer than usual duration from onset of symptoms to death. New variant CJD accounts for less than 1% of cases, and tends to affect younger people. It can result when someone is exposed to contaminated products. While classic CJD is not related to mad cow disease, new variant CJD (nvCJD) is an infectious form that is related to mad cow disease. The infection responsible for the disease in cows (bovine spongiform encephalitis) is believed to be the same one responsible for vCJD in humans. There have not been any cases of nvCJD reported in the U.S. Another variant, called the panencephalopathic form, occurs primarily in Japan and has a relatively long course, with symptoms often progressing for several years. Scientists are trying to gain a better understanding about what causes these variations in the symptoms and course of the disease. |
information | What is (are) Benign rolandic epilepsy (BRE) ? | Benign rolandic epilepsy is the most common form of childhood epilepsy. It is referred to as "benign" because most children outgrow the condition by puberty, usually by 14 years of age. This form of epilepsy is characterized by seizures involving the part of the frontal lobe of the brain called the rolandic area. The seizures associated with this condition typically occur during the nighttime. Treatment is usually not prescribed, since the condition tends to disappear by puberty. |
symptoms | What are the symptoms of Benign rolandic epilepsy (BRE) ? | What are the signs and symptoms of Benign rolandic epilepsy (BRE)? Patients with this syndrome typically present between the ages of 3 and 13 years with nighttime seizures. The episodes usually begin with twitching and stiffness of the face, and often wake up the child. The clonic activity causes a tingling feeling on one side of the mouth involving the tongue, lips, gum and inner side of the cheek. The seizure may also involve the throat which may make speech unclear and difficult to understand. Occasionally, both sides of the body may be affected, which can lead to loss of consciousness causing stiffness and jerking movements of the arms and legs. The child may also be incontinent. After an episode, a child may be sleepy and doze for a few hours. The Human Phenotype Ontology provides the following list of signs and symptoms for Benign rolandic epilepsy (BRE). If the information is available, the table below includes how often the symptom is seen in people with this condition.

causes | What causes Benign rolandic epilepsy (BRE) ? | What causes benign rolandic epilepsy? Benign rolandic epilepsy is a genetic syndrome with an autosomal dominant mode of inheritance. Although the gene associated with the condition has not been identified, Neubauer et al. (1998) found evidence of linkage to chromosome 15q. Juvenile myoclonic epilepsy has been mapped to the same region. |
treatment | What are the treatments for Benign rolandic epilepsy (BRE) ? | What treatment is available for benign rolandic epilepsy? Although treatment is usually not necessary since the episodes are infrequent and are typically outgrown by puberty, anticonvulsants such as carbamazepine. |
information | What is (are) Adult-onset Still's disease ? | Adult-onset Still's disease is an inflammatory condition characterized by high fevers, rash, sore throat, and joint pain. As it progresses, adult-onset Still's disease may lead to chronic arthritis and other complications. Still's disease was named after an English doctor named George Still, who described the condition in children in 1896. Still's disease which occurs in children (those under the age of 16) is now known as systemic onset juvenile rheumatoid arthritis (JRA). In 1971, the term "adult Still's disease" was used to describe adults who had a condition similar to systemic onset JRA. The cause of adult-onset Still's disease is unknown. No risk factors for the disease have been identified. There's no cure for adult-onset Still's disease; however, treatment may offer symptom relief and help prevent complications. |

information | What is (are) WAGR syndrome ? | WAGR syndrome is a genetic syndrome in which there is a predisposition to several conditions, including certain malignancies, distinctive eye abnormalities, and/or mental retardation. WAGR is an acronym for Wilms tumor, Aniridia, Genitourinary anomalies (such as undescended testicles or hypospadias in males, or internal genital or urinary anomalies in females), mental Retardation syndrome. A combination of two or more of these conditions is usually present in most individuals with WAGR syndrome. The syndrome is due to a microdeletion in the 11p13 region of chromosome 11. In most cases, this genetic change occurs spontaneously during early embryonic development (de novo) for unknown reasons (sporadic). Only rarely is the mutation inherited. |

information | What is (are) Primary orthostatic tremor ? | Primary orthostatic tremor is a movement disorder characterized by rhythmic muscle contractions that occur in the legs and trunk immediately after standing. It may be perceived more as an unsteadiness than an actual tremor. The tremor may disappear or improve when a person is sitting or walking. Over time, the tremors may become more severe, affecting quality of life and causing increasing disability. In some cases, primary orthostatic tremor may occur with other movement disorders. Individuals with primary orthostatic tremor may be treated with clonazepam and primidone. The cause of this condition is unknown. |

information | What is (are) Warthin tumor ? | Warthin tumor is a benign tumor of the salivary gland. The first symptom is usually a painless, slow-growing bump in front of the ear, on the bottom of the mouth, or under the chin. Warthin tumors may increase in size over time, but few become cancerous. Though the cause is currently unknown, smoking is believed to increase the chance of developing Warthin tumor. Treatment may consist of surgery to remove the tumor or careful observation to watch for changes in the tumor over time. |
symptoms | What are the symptoms of Warthin tumor ? | What are the signs and symptoms of Warthin tumor? Warthin tumor is a benign (noncancerous) tumor of the salivary glands. They most commonly arise in the parotid glands, the largest salivary glands which are located in each cheek above the jaw in front of the ears. Approximately 5-14% of cases are bilateral and 12-20% of affected people experience multicentric (more than one tumor which formed separately from one another) disease. The first symptom is usually a firm, painless bump. Without treatment, the swelling may gradually increase overtime which can cause facial nerve palsy (difficulty moving one side of the face). |
causes | What causes Warthin tumor ? | What causes Warthin tumor? The exact underlying cause of Warthin tumor is currently unknown. However, smoking is thought to increase the risk of developing the tumor. Some studies suggest that radiation exposure and autoimmune disorders may also be associated with Warthin tumor. |
exams and tests | How to diagnose Warthin tumor ? | How is Warthin tumor diagnosed? A diagnosis of Warthin tumor is often suspected based on the presence of characteristic signs and symptoms. The following tests may then be ordered to confirm the diagnosis and rule out other conditions that cause similar features: X-rays of the salivary gland (called a ptyalogram or sialogram) CT scan, MRI and/or ultrasound Salivary gland biopsy |
treatment | What are the treatments for Warthin tumor ? | How might Warthin tumor be treated? Treatment of Warthin tumor generally includes surgery to remove the tumor or careful observation to watch for changes in the tumor over time. Because Warthin tumor is almost always benign, additional treatment (i.e. radiation therapy and/or chemotherapy) is rarely needed. |
information | What is (are) Osteopetrosis autosomal recessive 5 ? | Osteopetrosis is a bone disease that makes bones abnormally dense and prone to breakage (fracture). Researchers have described several major types of osteopetrosis, which are usually distinguished by their pattern of inheritance: autosomal dominant, autosomal recessive, or X-linked. The different types of the disorder can also be distinguished by the severity of their signs and symptoms. Mutations in at least nine genes cause the various types of osteopetrosis. |

information | What is (are) Keratosis follicularis spinulosa decalvans ? | Keratosis follicularis spinulosa decalvans (KFSD) is a rare, inherited, skin condition. KFSD is a form of ichthyoses, a group of inherited conditions of the skin in which the skin tends to be thick and rough, and to have a scaly appearance. The face, neck, and forearms are frequently involved. The thickening of the skin is accompanied by the loss of eyebrows, eyelashes, and hair on the face and head. Allergic reactions (atopy), reduced tolerance of bright light (photophobia), and inflammation of the eye's cornea (keratitis) may also occur. KFSD is thought to be caused by mutations in the SAT1 gene and inherited in an X-linked manner. |

information | What is (are) Sudden infant death syndrome ? | Sudden infant death syndrome (SIDS) is the unexpected, sudden death of a child under age 1 which cannot be explained after a thorough investigation is conducted. Infants who are affected by the condition generally appear healthy with no suspicious signs and symptoms prior to the incident. It is the leading cause of death in infants age 1 to 12 months old. The exact underlying cause of SIDS is unknown; however, scientists suspect that it is likely a multifactorial condition (associated with the effects of multiple genes in combination with lifestyle and environmental factors). Although there is no guaranteed way to prevent SIDS, the American Academy of Pediatrics has a published list of recommendations for risk reduction. Please click on the link to access this resource. |
