symptoms | What are the symptoms of Charcot-Marie-Tooth disease type 2J ? | What are the signs and symptoms of Charcot-Marie-Tooth disease type 2J? The Human Phenotype Ontology provides the following list of signs and symptoms for Charcot-Marie-Tooth disease type 2J. 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 eye - Abnormality of the respiratory system - Areflexia - Autosomal dominant inheritance - Axonal degeneration/regeneration - Distal muscle weakness - Distal sensory impairment - Dysphagia - Foot dorsiflexor weakness - Hyporeflexia - Peripheral demyelination - Pes cavus - Progressive sensorineural hearing impairment - Sensorineural hearing impairment - Steppage gait - 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. |
information | What is (are) Dravet syndrome ? | Dravet syndrome is a severe form of epilepsy. The condition appears during the first year of life as frequent fever-related (febrile) seizures. As the condition progresses, other types of seizures typically occur, including myoclonus and status epilepticus. A family history of either epilepsy or febrile seizures exists in 15 percent to 25 percent of cases. Intellectual development begins to deteriorate around age 2, and affected individuals often have a lack of coordination, poor development of language, hyperactivity, and difficulty relating to others. In 30 to 80 percent of cases, Dravet syndrome is caused by changes in the SCN1A gene, which is required for the proper function of brain cells. |

information | What is (are) Charcot-Marie-Tooth disease type 2B ? | Charcot-Marie-Tooth disease type 2B (CMT2B) affects the peripheral nerves, the nerves running from outside the brain and spine. Common signs and symptoms include slowly progressive weakness and numbness in the feet, lower leg muscles, hands, and forearms. This type of CMT is also associated with the formation of ulcers in the hands and feet. Symptoms may start in childhood to early adulthood, although later onset (>50 years) has also been described. Symptoms of CMT2B vary but tend to be similar to that of CMT type 1. CMT2B is caused by changes in the RAB7A gene. It is inherited in an autosomal dominant fashion. |

information | What is (are) Generalized pustular psoriasis ? | Generalized pustular psoriasis is a severe inflammatory skin condition that can be life-threatening. Affected people develop episodes of red and tender skin with widespread pustules throughout their body. This is generally accompanied by fever, chills, headache, rapid pulse rate, loss of appetite, nausea and muscle weakness. The condition generally resolves within days or weeks; however, relapses are common. Some cases of generalized pustular psoriasis are caused by changes (mutations) in the IL36RN gene and are inherited in an autosomal recessive manner. Possible triggers for sporadic forms of the condition include withdrawal from corticosteroids, exposure to certain medications, and/or infection; however, in many cases, the underlying cause is unknown. Generalized pustular psoriasis can be life threatening, so hospitalization and a specialist's care is usually required. Affected areas are treated with topical (on the skin) compresses with emollients and/or steroid creams. Certain medications may also be recommended to manage non-skin-related symptoms. |

information | What is (are) Salivary gland cancer, adult ? | Salivary gland cancer is a rare disease in which cancerous cells form in the tissues of the salivary glands. The salivary glands make saliva and release it into the mouth. Saliva has enzymes that help to digest food and antibodies that help protect against infections of the mouth and throat. There are 3 pairs of major salivary glands: the parotid glands, the sublingual glands, and the submandibular glands. The National Cancer Institute provides a picture of the anatomy of the salivary glands. Some risk factors for salivary gland cancer are older age, exposure to radiation of the head and/or neck area, and family history. Signs and symptoms of the disease may include: a lump near the ear, cheek, jaw, lip, or inside of the mouth; trouble swallowing; fluid draining from the ear; numbness or weakness in the face; and on-going pain in the face. Different types of treatment are available for patients with salivary gland cancer. Some treatments are standard (currently used by physicians) and some are being tested in clinical trials (by researchers). It is suggested that patients with salivary gland cancer have their treatment planned and managed by a team of doctors who are experts in treating head and neck cancer. Although treatment depends on the stage of the cancer, typically the following three treatments are used: (1) surgery, (2) radiation therapy, and (3) chemotherapy. [1] [2] |

information | What is (are) Wolff-Parkinson-White syndrome ? | Wolff-Parkinson-White syndrome is a condition that disrupts the heart's normal rhythm (arrhythmia). People with Wolff-Parkinson-White syndrome are born with a heart abnormality that affects the coordinated movement of electrical signals through the heart. This abnormality leads to an abnormally fast heartbeat (tachycardia) and other arrhythmias. In most cases, the cause of Wolff-Parkinson-White syndrome is unknown. A small percentage of cases are caused by mutations in the PRKAG2 gene. These cases appear to be inherited in an autosomal dominant manner. |

causes | What causes Wolff-Parkinson-White syndrome ? | What causes Wolff-Parkinson-White syndrome? Normally, electrical signals in the heart go through a pathway that helps the heart beat regularly. The wiring of the heart prevents extra beats from occurring and keeps the next beat from happening too soon. In people with Wolff Parkinson White syndrome, there is an extra, or accessory, pathway that may cause a very rapid heart rate. This extra electrical pathway is present at birth. A mutation in the PRKAG2 gene is the cause of a small percentage of cases of the disorder. Otherwise, little is known about why this extra pathway develops. |

information | What is (are) Landau-Kleffner syndrome ? | Landau-Kleffner syndrome (LKS) is a rare, childhood neurological disorder characterized by the sudden or gradual development of aphasia (the inability to understand or express language) and an abnormal electro-encephalogram (EEG). The disorder usually occurs in children between age 2 and 8. Typically, children with LKS develop normally but then lose their language skills for no apparent reason. While many of the affected individuals have seizures, some do not. The disorder is difficult to diagnose and may be misdiagnosed as autism, pervasive developmental disorder, hearing impairment, learning disability, auditory/verbal processing disorder, attention deficit disorder, intellectual disability, childhood schizophrenia, or emotional/behavioral problems. Treatment for LKS usually consists of medications, such as anticonvulsants and corticosteroids, and speech therapy, which should be started promptly. The prognosis varies. Some children may have a permanent language disorder, while others may regain much of their language abilities (although it may take months or years). |
symptoms | What are the symptoms of Landau-Kleffner syndrome ? | What are the signs and symptoms of Landau-Kleffner syndrome? Landau-Kleffner syndrome is characterized by the sudden or gradual development of aphasia (the inability to understand or express language) in previously normal children along with an abnormal electro-encephalogram (EEG). It most frequently occurs in children between the ages of 2 and 8. The condition affects the part of the brain that controls comprehension and speech. Some children with Landau-Kleffner syndrome develop behavioral problems, including hyperactivity, attention deficits, temper outbursts, impulsivity, and/or withdrawn behaviors. Seizures occur in up to 2/3 of affected children. These complex partial, generalized clonic and atypical absence seizures are generally easy to control and often resolve spontaneously before adolescence. The Human Phenotype Ontology provides the following list of signs and symptoms for Landau-Kleffner syndrome.

information | What is (are) Hypolipoproteinemia ? | Hypolipoproteinemia refers to unusually low levels of fats (lipids) in the blood. Low lipid levels may be caused by rare genetic conditions, or be a sign of another disorder such as overactive thyroid, anemia, undernutrition, cancer, chronic infection, or impaired absorption of foods from the digestive tract. Associated genetic disorders includes abetalipoproteinemia, hypobetalipoproteinemia, and chylomicron retention disease. Symptoms of the genetic or familial form of hypolipoproteinemia varies. In hypobetalipoproteinemia the low density lipoprotein (LDL) cholesterol levels are very low, yet people with this syndrome typically have no symptoms nor require treatment. Other forms result in absent or near absent LDL levels and can cause serious symptoms in infancy and early childhood. |
symptoms | What are the symptoms of Hypolipoproteinemia ? | Are there other symptoms associated with hypolipoproteinemia? Some reports suggest that hypolipoproteinemia (low cholesterol levels) in general may increase the risk for development of fatty livers. |
causes | What causes Hypolipoproteinemia ? | What causes familial or genetic hypolipoproteinemia? Cholesterol levels in general are thought to be influenced by genetic factors. Very low levels of lipids (hypolipoproteinemia) is known to be caused by certain genetic conditions, including hypobetalipoproteinemia, abetalipoproteinemia, and chylomicron retention disease. Hypobetalipoproteinemia is inherited in an autosomal dominant fashion. Autosomal dominant inheritance is when one mutated copy of the gene that causes a disorder in each cell is needed for a person to be affected. Each affected person usually has one affected parent. Autosomal dominant disorders tend to occur in every generation of an affected family. When a person with an autosomal dominant disorder has a child, there is a 50% chance that their child will inherit the condition. In some families the condition is due to mutations in a gene called APOB, in other families the underlying mutation has not been identified. People with this condition usually do not experience symptoms. People who inherit two hypobetalipoproteinemia gene mutations may have extremely low levels of low-density lipoprotein cholesterol (LDL-C) and apolipoprotein B (apoB). Some of these individuals have no symptoms while others have developed fatty liver, intestinal fat malabsorption, and neurological problems. Abetalipoproteinemia is a rare disorder with approximately 100 cases described worldwide. Mutations in the MTTP gene cause abetalipoproteinemia. It is passed through families in an autosomal recessive pattern. Click here to learn more about autosomal recessive inheritance. The signs and symptoms of abetalipoproteinemia may include failure to thrive, diarrhea, abnormal star-shaped red blood cells, and fatty, foul-smelling stools in infants, nervous system impairment in children, retinitis pigmentosa and difficulty with balance and walking in childhood or adulthood. Chylomicron retention disease is a rare condition with approximately 40 cases described worldwide and is also inherited in an autosomal recessive pattern. The signs and symptoms appear in the first few months of life and may include failure to thrive, diarrhea, fatty, foul-smelling stools, and later nervous system impairment. Other genetic conditions characterized by hypolipoproteinemia include, but is not limited to: Lecithin acyltransferase deficiency Tangier Disease |
information | What is (are) Notalgia paresthetica ? | Notalgia paresthetica is a common chronic, localized itch, that usually affects patches of skin on the upper back. Occasionally be more widespread and involve other parts of the back, the shoulders and upper chest. People feel both the sensation of an itch and paresthesia (a sensation of tingling, pricking, or numbness of the skin). There are no signs on the skin except for signs of chronic scratching and rubbing. Amyloid deposits (a collection of a specific type of protein) may be found in skin biopsies, but this is thought to be a secondary event. The cause of the itch in notalgia paresthetica may be due to the compression of spinal nerves by bones or muscles as the nerves emerge through the vertebrae to the back muscles. Sometimes degenerative changes in the area of the vertebrae that innervate the affected back muscles can be seen, but not always. Symptoms of notalgia paresthetica may respond to topical capsaicin treatment. |
treatment | What are the treatments for Notalgia paresthetica ? | How might notalgia paresthetica be treated? While this condition may be difficult to treat, typical neuralgia therapies are often employed with moderate success. Effective measures may include: Cooling lotions as required (camphor and menthol) Capsaicin cream - this depletes nerve endings of their chemical transmitters Local anaesthetic creams Amitriptyline tablets at night Transcutaneous electrical nerve stimulation (TENS) Gabapentin Oxcarbazepine Botulinum toxin Phototherapy Exercise Additional information about treatment of notalgia paresthetica can be accessed by clicking here. You can find relevant journal articles on treatment of notalgia paresthetica through a service called PubMed, a searchable database of medical literature. Information on finding an article and its title, authors, and publishing details is listed here. Some articles are available as a complete document, while information on other studies is available as a summary abstract.

information | What is (are) Congenital adrenal hyperplasia ? | Congenital adrenal hyperplasia (CAH) refers to a group of genetic conditions that affect the adrenal glands. These glands sit on top of the kidneys and are responsible for releasing various types of hormones that the body needs to function. Affected people lack an enzyme the adrenal glands need to make one or more of these hormones and often overproduce androgens (male hormones such as testosterone). The signs and symptoms present in each person depend on many factors including the type of CAH, the age of diagnosis, and the sex of the affected person. For example, females with a severe form of the condition may have ambiguous genitalia at birth and if not properly diagnosed, develop dehydration, poor feeding, diarrhea, vomiting and other health problems soon after. People with milder forms may not be diagnosed with the condition until adolescence or adulthood when they experience early signs of puberty or fertility problems. Treatment for CAH varies but may include medication and/or surgery. |
symptoms | What are the symptoms of Congenital adrenal hyperplasia ? | What are the signs and symptoms of Congenital adrenal hyperplasia? The signs and symptoms of congenital adrenal hyperplasia (CAH) vary based on many factors including the type of CAH, the age of diagnosis and the sex of the affected person. For example, girls with the severe form of CAH may be born with ambiguous genitalia, which often allows the condition to be diagnosed before other associated health problems such as poor feeding, vomiting, dehydration, and abnormal heart beat, can develop. Males typically appear unaffected at birth even when they have a severe form of CAH and without proper diagnosis, will develop associated health problems within 2-3 weeks after birth. Both genders can experience other symptoms such as early onset of puberty, fast body growth, and premature completion of growth leading to short stature, if they are not treated in early life. People affected by milder forms may not have any signs and symptoms of CAH during childhood. In these cases, a diagnosis may not be made until adolescence or adulthood when the affected person experiences early signs of puberty or fertility problems. Females with this type may have excessive facial or body hair; irregular menstrual periods; and/or acne. There are two main types of CAH: classic CAH, the more severe form, and a milder form called nonclassic CAH. For a detailed description of the signs and symptoms found in each type of CAH, please click here.

causes | What causes Congenital adrenal hyperplasia ? | What causes congenital adrenal hyperplasia? Congenital adrenal hyperplasia (CAH) is a group of genetic conditions that can be caused by a change (mutation) in several different genes: 21-hydroxylase deficiency is caused by mutations in the CYP21A2 gene 3-beta-hydroxysteroid dehydrogenase deficiency is caused by mutations in the HSD3B2 gene 11-beta-hydroxylase deficiency is caused by mutations in the CYP11B1 gene Cytochrome P450 oxidoreductase deficiency is caused by mutations in the POR gene 17-hydroxylase deficiency is caused by mutations in the CYP17A1 gene Congenital lipoid adrenal hyperplasia is caused by mutations in the STAR gene Most of these genes encode enzymes that the adrenal glands need to make one or more hormones. The adrenal glands are cone-shaped organs that sit on top of the kidneys and are responsible for releasing various types of hormones that the body needs to function. Mutations in these genes lead to deficient levels of enzymes which cause low levels of hormones such as cortisol and/or aldosterone and an overproduction of androgens (male hormones such as testosterone). Cortisol is a hormone that affects energy levels, blood sugar levels, blood pressure, and the body's response to stress, illness, and injury. Aldosterone helps the body maintain the proper level of sodium (salt) and water and helps maintain blood pressure. Irregular levels of these hormones lead to the signs and symptoms of CAH. |
inheritance | Is Congenital adrenal hyperplasia inherited ? | How is congenital adrenal hyperplasia inherited? All forms of congenital adrenal hyperplasia (CAH) are inherited in an autosomal recessive manner. This means that to be affected, a person must have a mutation in both copies of the responsible gene in each cell. The parents of an affected person usually each carry one mutated copy of the gene and are referred to as carriers. Carriers typically do not show signs or symptoms of the condition. When two carriers of an autosomal recessive condition have children, each child has a 25% (1 in 4) risk to have the condition, a 50% (1 in 2) risk to be a carrier like each of the parents, and a 25% chance to not have the condition and not be a carrier. |
exams and tests | How to diagnose Congenital adrenal hyperplasia ? | Is genetic testing avaliable for congenital adrenal hyperplasia? Yes, genetic testing is available for many of the genes known to cause congenital adrenal hyperplasia (CAH). Carrier testing for at-risk relatives and prenatal testing are possible if the disease-causing mutations in the family are known. The Genetic Testing Registry (GTR) is a centralized online resource for information about genetic tests. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional. How is congenital adrenal hyperplasia diagnosed? Shortly after birth, all newborns in the United States are screened for a variety of conditions, including 21-hydroxylase deficiency. This is the most common cause of congenital adrenal hyperplasia (CAH) and accounts for 95% of classic CAH cases. Nonclassic CAH is not detected through newborn screening and is often not suspected until signs and symptoms of the condition begin to appear later in childhood or early adulthood. In these cases, a diagnosis of CAH is usually based on physical examination; blood and urine tests that measure hormone levels; and/or genetic testing. An X-ray may also be helpful in confirming the diagnosis in children since CAH can cause bones to grow and develop more quickly than usual (advanced bone age) . |
treatment | What are the treatments for Congenital adrenal hyperplasia ? | How might congenital adrenal hyperplasia be treated? The best treatment options for congenital adrenal hyperplasia (CAH) depend on many factors including the type of CAH and the signs and symptoms present in each person. Many people with CAH require steroids to replace the low hormones. These medications will need to be taken daily throughout life or the symptoms of CAH may return. It is important that affected people on medications be closely followed by their healthcare provider because their dose may need to be adjusted at different times in life such as periods of high stress or illness. Girls with severe CAH who are born with ambiguous genitalia may undergo surgery to ensure proper function and/or to make the genitals look more female.

information | What is (are) Medium-chain acyl-coenzyme A dehydrogenase deficiency ? | Medium-chain acyl-coenzyme A dehydrogenase deficiency (MCADD) is an inherited metabolic disorder that prevents the body from converting certain fats to energy, particularly during periods without food (fasting). Normally, through a process called fatty acid oxidation, several enzymes work in a step-wise fashion to break down (metabolize) fats and convert them to energy. People with MCADD do not have enough of an enzyme needed for the step that metabolizes a group of fats called medium-chain fatty acids. MCADD is caused by mutations in the ACADM gene and is inherited in an autosomal recessive manner. Treatment includes avoidance of fasting and of medium chain triglycerides in the diet. |
symptoms | What are the symptoms of Medium-chain acyl-coenzyme A dehydrogenase deficiency ? | What are the signs and symptoms of Medium-chain acyl-coenzyme A dehydrogenase deficiency? The initial signs and symptoms of medium-chain acyl-coenzyme A dehydrogenase deficiency (MCADD) typically occur during infancy or early childhood and can include vomiting, lack of energy (lethargy), and low blood sugar (hypoglycemia). In rare cases, the first episode of problems related to MCADD occurs during adulthood. The signs and symptoms of MCADD can be triggered by periods of fasting, or during illnesses such as viral infections, particularly when eating is reduced. People with MCADD are also at risk of serious complications such as seizures, breathing difficulties, liver problems, brain damage, coma, and sudden, unexpected death. The Human Phenotype Ontology provides the following list of signs and symptoms for Medium-chain acyl-coenzyme A dehydrogenase deficiency.

In these cases, the sign or symptom may be rare or common. |
causes | What causes Medium-chain acyl-coenzyme A dehydrogenase deficiency ? | What causes medium-chain acyl-coenzyme A dehydrogenase (MCAD) deficiency? Mutations in the ACADM gene cause medium-chain acyl-coenzyme A dehydrogenase deficiency. Mutations in the ACADM gene lead to inadequate levels of an enzyme called medium-chain acyl-coenzyme A dehydrogenase. Without sufficient amounts of this enzyme, medium-chain fatty acids from food and fats stored in the body are not metabolized properly. As a result, these fats are not converted to energy, which can lead to characteristic signs and symptoms of this disorder such as lethargy and low blood sugar. Medium-chain fatty acids or partially metabolized fatty acids may accumulate in tissues and can damage the liver and brain, causing serious complications. |
inheritance | Is Medium-chain acyl-coenzyme A dehydrogenase deficiency inherited ? | How is medium-chain acyl-coenzyme A dehydrogenase (MCAD) deficiency inherited? Medium-chain acyl-coenzyme A dehydrogenase deficiency (MCADD) is inherited in an autosomal recessive manner. This means that both copies of the responsible gene in each cell must have mutations for a person to be affected. Usually, the parents of a person with an autosomal recessive condition each have one mutated copy of the gene and are referred to as carriers. Carriers typically do not have any signs or symptoms of the condition. When two carriers of an autosomal recessive condition have children, each child has a 25% (1 in 4) chance to be affected, a 50% (1 in 2) chance to be a carrier like each parent, and a 25% chance to be unaffected and not be a carrier. |
exams and tests | How to diagnose Medium-chain acyl-coenzyme A dehydrogenase deficiency ? | How is medium-chain acyl-coenzyme A dehydrogenase deficiency (MCADD) diagnosed? MCADD is now included in many newborn screening programs. If a newborn screening result for MCADD is not in the normal range, additional testing is recommended. A diagnosis of MCADD can be made through a blood test called a plasma acylcarnitine profile and an evaluation of organic acids in the urine. The diagnosis can also be confirmed by genetic testing. |
information | What is (are) Non-involuting congenital hemangioma ? | Non-involuting congenital hemangioma (NICH) is a rare type of infantile hemangioma, which is a tumor that forms from the abnormal growth of blood vessels in the skin. NICH looks like an oval, purplish mark or bump that can occur on any part of the body. NICH is present from birth (congenital) and increases in size as the child grows. Unlike other hemangiomas, NICH do not disappear spontaneously (involute). |
exams and tests | How to diagnose Non-involuting congenital hemangioma ? | How is non-involuting congenital hemangioma diagnosed? Non-involuting congenital hemangioma (NICH) is diagnosed by taking a biopsy of the skin mark and examining the tissue under a microscope. NICH looks different under the microscope than most infantile hemangiomas because the blood vessels are arranged more irregularly. Also, the cells in an NICH do not have glucose receptors, whereas the cells of almost all hemangiomas do have glucose receptors. Finally, NICH is different from more common types of hemangiomas because NICH does not spontaneously disappear (involute). Instead, NICH remains stable over time. |
treatment | What are the treatments for Non-involuting congenital hemangioma ? | How might non-involuting congenital hemangioma treated? Because non-involuting congenital hemangioma (NICH) is quite rare, there are no established guidelines for the treatment of this condition. However, the authors of one article on NICH suggest that there is no risk for excessive bleeding during the removal of an NICH and it is unlikely to regrow after surgery. Because NICH is a benign skin mark, surgery isn't necessary but can be considered to improve appearance of the skin. |
information | What is (are) Proteus-like syndrome ? | Proteus-like syndrome describes people who do not meet the diagnostic criteria for Proteus syndrome but who share many of the characteristic signs and symptoms associated with the condition. Affected people may experience some of the following features: overgrowth of the bones, skin, and other tissues; hamartomas; abnormalities of the skin, blood vessels (vascular tissue) and fat (adipose tissue); and distinctive facial features. Approximately 50% of people with Proteus-like syndrome are found to have changes (mutations) in the PTEN gene. In these cases, the inheritance is autosomal dominant. Treatment is based on the signs and symptoms present in each person. |

information | What is (are) Chromosome 16q deletion ? | Chromosome 16q deletion is a chromosome abnormality that occurs when there is a missing (deleted) copy of genetic material on the long arm (q) of chromosome 16. The severity of the condition and the signs and symptoms depend on the size and location of the deletion and which genes are involved. Features that often occur in people with chromosome 16q deletion include developmental delay, intellectual disability, behavioral problems and distinctive facial features. Chromosome testing of both parents can provide more information on whether or not the deletion was inherited. In most cases, parents do not have any chromosomal anomaly. However, sometimes one parent is found to have a balanced translocation, where a piece of a chromosome has broken off and attached to another one with no gain or loss of genetic material. The balanced translocation normally does not cause any signs or symptoms, but it increases the risk for having an affected child with a chromosomal anomaly like a deletion. Treatment is based on the signs and symptoms present in each person. This page is meant to provide general information about 16q deletions. You can contact GARD if you have questions about a specific deletion on chromosome 16. To learn more about chromosomal anomalies please visit our GARD webpage on FAQs about Chromosome Disorders. |

inheritance | Is Corneal endothelial dystrophy type 2 inherited ? | How is corneal endothelial dystropy type 2 inherited? Most cases of corneal endothelial dystrophy type 2 are caused by homozygous mutations in the SLC4A11 gene. The condition is transmitted in an autosomal recessive manner. This means that two unaffected parents each carry one copy of a gene mutation for the condition. Neither parent will show signs or symptoms of the condition because two copies are needed for the condition to occur. There have been several families with corneal endothelial dystrophy type 2 where no mutation was found in the SLC4A11 gene.

causes | What causes Cri du chat syndrome ? | What causes cri du chat syndrome? Cri du chat syndrome is caused by a deletion of the end of the short (p) arm of chromosome 5. This chromosomal change is written as 5p-. The size of the deletion varies among affected individuals but studies suggest that larger deletions tend to result in more severe intellectual disability and developmental delay than smaller deletions. The signs and symptoms of cri du chat syndrome are probably related to the loss of multiple genes on the short arm of chromosome 5. Researchers believe that the loss of a specific gene, CTNND2, is associated with severe intellectual disability in some people with this condition. They are working to determine how the loss of other genes in this region contributes to the characteristic features of cri du chat syndrome. |
inheritance | Is Cri du chat syndrome inherited ? | Is cri du chat syndrome inherited? Most cases of cri du chat syndrome are not inherited. The deletion occurs most often as a random event during the formation of reproductive cells (eggs or sperm) or in early fetal development. Most affected individuals do not have a history of the disorder in their family. About 10 percent of people with cri du chat syndrome inherit the chromosome abnormality from an unaffected parent. In these cases, the parent carries a chromosomal rearrangement called a balanced translocation, in which no genetic material is gained or lost. Balanced translocations usually do not cause any health problems; however, they can become unbalanced as they are passed to the next generation. Children who inherit an unbalanced translocation can have a chromosomal rearrangement with extra or missing genetic material. Individuals with cri du chat syndrome who inherit an unbalanced translocation are missing genetic material from the short arm of chromosome 5. This results in the intellectual disability and other health problems characteristic of the disorder. |
treatment | What are the treatments for Cri du chat syndrome ? | How might cri du chat syndrome be treated? While there is no specific treatment available for cri du chat syndrome, early intervention is recommended in the areas of physical therapy (achieving physical and motor milestones such as sitting and standing up), communication (speech therapy, sign language instruction), behavioral modification (for hyperactivity, short attention span, aggression), and learning (special education). Because symptoms may vary from individual to individual, we recommend discussing these options with a health care professional to develop a personalized plan for therapy. |
information | What is (are) Complement component 2 deficiency ? | Complement component 2 deficiency (C2D) is a genetic condition that affects the immune system. Signs and symptoms include recurrent bacterial infections and risk for a variety of autoimmune conditions. Infections can be very serious and are common in early life. They become less frequent during the teen and adult years. The most frequent autoimmune conditions associated with C2D are lupus (10-20%) and vasculitis. C2D is caused by mutations in the C2 gene and is inherited in an autosomal recessive fashion. |

information | What is (are) Citrullinemia type I ? | Citrullinemia type I is an inherited disorder that causes ammonia and other toxic substances to accumulate in the blood. This condition, also known as classic citrullinemia, belongs to a class of genetic diseases called urea cycle disorders. In most cases, the condition becomes evident in the first few days of life. Affected infants typically appear normal at birth, but as ammonia builds up in the body they experience a progressive lack of energy (lethargy), poor feeding, vomiting, seizures, and loss of consciousness. Citrullinemia type I is caused by mutations in the ASS1 gene. It is inherited in an autosomal recessive pattern. |
symptoms | What are the symptoms of Citrullinemia type I ? | What are the signs and symptoms of Citrullinemia type I? Citrullinemia type I presents as a clinical spectrum that includes an acute neonatal form, a milder late-onset form, a form without symptoms and/or hyperammonemia, and a form in which women have onset of severe symptoms during pregnancy or post partum. Infants with the acute neonatal form typically appear normal at birth, but as ammonia builds up in the body they become progressively lethargic, feed poorly, vomit, and develop signs of increased intracranial pressure, which can lead to seizures and loss of consciousness. Less commonly, a milder form of citrullinemia type I can develop later in childhood or adulthood. This later-onset form is associated with intense headaches, partial loss of vision, slurred speech, problems with balance and muscle coordination (ataxia), behavior problems, and lethargy. Episodes of high blood ammonia often happen after going without food for long periods of time, during illness or infection or after high-protein meals. Some people with gene mutations that cause citrullinemia type I never experience signs and symptoms of the disorder and are only found to be affected after a brother or sister is diagnosed. The Human Phenotype Ontology provides the following list of signs and symptoms for Citrullinemia type I. If the information is available, the table below includes how often the symptom is seen in people with this condition.

In these cases, the sign or symptom may be rare or common. |
causes | What causes Citrullinemia type I ? | What causes citrullinemia type I? Citrullinemia type I is caused by mutations in the ASS1 gene. This gene provides instructions for making an enzyme, argininosuccinate synthetase 1, that is responsible for the third step in the urea cycle. Mutations in the ASS1 gene reduce the activity of the enzyme, which disrupts the urea cycle and prevents the body from processing nitrogen effectively. Excess nitrogen (in the form of ammonia) and other byproducts of the urea cycle accumulate in the bloodstream. Ammonia is particularly toxic to the nervous system, which helps explain the neurologic symptoms (such as lethargy, seizures, and ataxia) that are often seen in this condition. |
inheritance | Is Citrullinemia type I inherited ? | How is citrullinemia type I inherited? Citrullinemia type I is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition. |
treatment | What are the treatments for Citrullinemia type I ? | What happens when citrullinemia type I is not treated? Untreated individuals with the severe form of citrullinemia type I have hyperammonemia (plasma ammonia concentration 1000-3000 mol/L). Without prompt intervention, hyperammonemia and the accumulation of other toxic metabolites result in swelling of the brain, breathing problems, increased or decreased muscle tone, muscle weakness, problems staying warm, seizures, loss of consciousness, and sometimes death. Without treatment, most babies die within the first few weeks of life. |
information | What is (are) Hyper-IgD syndrome ? | Hyper IgD syndrome is an inflammatory genetic disorder characterized by periodic episodes of fever associated with additional symptoms including joint pain, skin rash and abdominal pain. Most episodes last several days and occur periodically throughout life. The frequency of episodes and their severity vary greatly from case to case. Hyper IgD syndrome is caused by mutations in the gene encoding mevalonate kinase (MVK). It is inherited in an autosomal recessive manner. |
symptoms | What are the symptoms of Hyper-IgD syndrome ? | What are the signs and symptoms of Hyper-IgD syndrome? Hyper IgD syndrome is characterized by periodic high fevers accompanied by lymphadenopathy, abdominal pain, diarrhea, headache, joint pain, hepatomegaly and/or splenomegaly, and skin lesions.

information | What is (are) Schimke immunoosseous dysplasia ? | Schimke immunoosseous dysplasia (SIOD) is a condition characterized by short stature, kidney disease, and a weakened immune system. Growth failure is often the first sign of this condition. Other features are usually detected in the evaluation for growth failure or in the following years. The severity of SIOD ranges from an infantile or severe early-onset form to a juvenile or milder late-onset form. Complications of the severe form of SIOD can include strokes, severe opportunistic infections, bone marrow failure, and kidney failure that can be life-threatening early in life. People with milder disease have survived to adulthood if their kidney disease is managed. This condition is inherited in an autosomal recessive pattern. Mutations in the SMARCAL1 gene increase the risk to develop Schimke immunoosseous dysplasia. However, in order for people with SMARCAL1 gene mutations to develop symptoms of Schimke immunoosseous dysplasia, other currently unknown genetic or environmental factors must also be present. |
symptoms | What are the symptoms of Schimke immunoosseous dysplasia ? | What are the signs and symptoms of Schimke immunoosseous dysplasia? Schimke immunoosseous dysplasia is characterized by short stature, kidney disease, and a weakened immune system. In people with this condition, short stature is caused by flattened spinal bones (vertebrae), resulting in a shortened neck and trunk. Adult height is typically between 3 and 5 feet. Kidney (renal) disease often leads to life-threatening renal failure and end-stage renal disease (ESRD). Affected individuals also have a shortage of certain immune system cells called T cells. T cells identify foreign substances and defend the body against infection. A shortage of T cells causes a person to be more susceptible to illness. Other features frequently seen in people with this condition include an exaggerated curvature of the lower back (lordosis); darkened patches of skin (hyperpigmentation), typically on the chest and back; and a broad nasal bridge with a rounded tip of the nose. Less common signs and symptoms of Schimke immuno-osseous dysplasia include an accumulation of fatty deposits and scar-like tissue in the lining of the arteries (atherosclerosis), reduced blood flow to the brain (cerebral ischemia), migraine-like headaches, an underactive thyroid gland (hypothyroidism), decreased numbers of white blood cells (lymphopenia), underdeveloped hip bones (hypoplastic pelvis), abnormally small head size (microcephaly), a lack of sperm (azoospermia) in males, and irregular menstruation in females. In severe cases, many signs of Schimke immuno-osseous dysplasia can be present at birth. People with mild cases of this disorder may not develop signs or symptoms until late childhood. The Human Phenotype Ontology provides the following list of signs and symptoms for Schimke immunoosseous dysplasia.

The most definitive diagnostic findings are skeletal dysplasia (spondyloepiphyseal dysplasia), renal dysfunction (urinary protein loss), T lymphocyte deficiency, characteristic facial features, and hyperpigmented macules. DNA testing for mutations in SMARCAL1 is available on a clinical basis. |
treatment | What are the treatments for Schimke immunoosseous dysplasia ? | How might Schimke immunoosseous dysplasia be treated? Treatment of Schimke immunoosseous dysplasia (SIOD) is based on addressing individual symptoms as they develop. Renal transplantation can treat the renal disease, and bone marrow transplantation has been done to treat the immunodeficiency. Blood thinning medications can transiently improve blood flow through the atherosclerotic arteries but do not provide enduring relief from cerebral ischemia. Treatment with acyclovir and some antibacterial agents has been beneficial for preventing of reducing the frequency of opportunistic infections. More detailed information about treatment for SIOD can be found on the GeneReview's Web site. Click on the GeneReview link to read more. |

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) Babinski sign - Facial hypotonia - Hyperreflexia - Hypoplasia of the maxilla - Intellectual disability - Juvenile onset - Low frustration tolerance - Lower limb amyotrophy - Lower limb muscle weakness - Mood swings - Motor aphasia - Restlessness - Short distal phalanx of finger - Shuffling gait - Spastic paraplegia - Strabismus - Urinary bladder sphincter dysfunction - Urinary incontinence - Urinary urgency - Visual impairment - X-linked recessive inheritance - 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. |
information | What is (are) Pyruvate carboxylase deficiency ? | Pyruvate carboxylase deficiency is an inherited disorder that causes lactic acid and other potentially toxic compounds to accumulate in the blood. High levels of these substances can damage the body's organs and tissues, particularly in the nervous system. Researchers have identified at least three types of pyruvate carboxylase deficiency, types A, B, and C, which are distinguished by the severity of their signs and symptoms. This condition is caused by mutations in the PC gene and inherited in an autosomal recessive pattern. |

inheritance | Is Pyruvate carboxylase deficiency inherited ? | How is pyruvate carboxylase deficiency inherited? Pyruvate carboxylase deficiency is inherited in an autosomal recessive manner. This means that both copies of the disease-causing gene in each cell (usually one inherited from each parent) must have a mutation for an individual to be affected. Individuals who carry one mutated copy of the gene are referred to as carriers. Carriers typically do not have any signs or symptoms of the condition. When two carriers for an autosomal recessive condition have children, each child has a 25% (1 in 4) risk to have the condition, a 50% (1 in 2) risk to be an unaffected carrier like each of the parents, and a 25% risk to not have the condition and not be a carrier (i.e. to inherit both normal genes). In other words, each child born to two carriers has a 75% (3 in 4) chance to be unaffected. De novo mutations (new mutations that occur for the first time in an individual and are not inherited from a parent) have been reported for this condition. This means that in some cases, an affected individual may have only one parent who is a carrier for the condition. Carrier testing for at-risk relatives and prenatal testing for pregnancies at increased risk may be possible through laboratories offering custom mutation analysis if the disease-causing mutations in a family are known. Individuals interested in learning more about genetic risks to themselves or family members, or about genetic testing for this condition, should speak with a genetics professional. |
information | What is (are) Zellweger spectrum ? | Zellweger spectrum refers to a group of related conditions that have overlapping signs and symptoms and affect many parts of the body. The spectrum includes Zellweger syndrome (ZS), the most severe form; neonatal adrenoleukodystrophy (NALD), an intermediate form; and infantile Refsum disease (IRD), the least severe form. Signs and symptoms of ZS typically become apparent in the newborn period and may include hypotonia, feeding problems, hearing and vision loss, seizures, distinctive facial characteristics, and skeletal abnormalities. Individuals with ZS often do not survive past the first year of life. The features of NALD and IRD often vary in nature and severity, and may not become apparent until late infancy or early childhood. Individuals with NALD or IRD may have hypotonia, vision and/or hearing problems, liver dysfunction, developmental delay and learning disabilities. Most individuals with NALD survive into childhood, and those with IRD may reach adulthood. Conditions in the Zellweger spectrum are caused by mutations in any of at least 12 genes and are inherited in an autosomal recessive manner. Treatment typically focuses on the specific signs and symptoms present in each individual. |

information | What is (are) Congenitally corrected transposition of the great arteries ? | Congenitally corrected transposition of the great arteries is a rare heart defect that occurs when the ventricles and attached valves are switched. As a result, the aorta and the pulmonary artery are connected to the wrong lower heart chambers. Click here to visit MayoClinic.com and view an image of this heart defect. While the oxygen-poor blood still flows to the lungs, and oxygen-rich blood still flows out to nourish the body, other heart problems (such as septal defects, pulmonary stenosis, tricuspid regurgitation, and heart block) are often associated with this defect and require treatment. |
causes | What causes Congenitally corrected transposition of the great arteries ? | What causes congenitally corrected transposition of the great arteries? Currently the cause of congenitally corrected transposition of the great arteries is not known. Limited data suggests that air pollutants and hair dye may act as environmental risk factors for this rare defect. Also, having a family history of this heart defect is a risk factor. It has been estimated that the recurrence risk in siblings is around 3% to 5%. |
information | What is (are) Acute alcohol sensitivity ? | Alcohol intolerance is characterized by immediate unpleasant reactions after drinking alcohol. The most common signs and symptoms of alcohol intolerance are stuffy nose and skin flushing. Alcohol intolerance is caused by a genetic condition in which the body is unable to break down alcohol efficiently, usually found in Asians. These individuals accumulate acetaldehyde, the primary metabolite of ethanol, because of a genetic polymorphism of aldehyde dehydrogenase (ALDH) that metabolizes acetaldehyde to nontoxic acetate.[9184] The only way to prevent alcohol intolerance reactions is to avoid alcohol. Alcohol intolerance isn't an allergy. However, in some cases, what seems to be alcohol intolerance may be a reaction to something in an alcoholic beverage, such as chemicals, grains or preservatives. Combining alcohol with certain medications also can cause reactions. In rare instances, an unpleasant reaction to alcohol can be a sign of a serious underlying health problem that requires diagnosis and treatment. |

information | What is (are) Sclerosing mucoepidermoid carcinoma with eosinophilia ? | Sclerosing mucoepidermoid carcinoma with eosinophilia (SMECE) is a type of cancer that most commonly affects the thyroid gland, but has been reported in the salivary gland as well. Signs and symptoms include a painless neck mass. Many people with mucoepidermoid carcinomas are women with Hashimoto's thyroiditis. The prevalence of SMECE is unknown, but only around 50 cases have been described in the medical literature. SMECE most commonly presents between 40 to 75 years of age. SMECE was initially considered a "low-grade" tumor, however cases of SMECE spreading locally to lymph nodes and to distant organs have been described. While data is limited, with treatment it appears that prognosis is typically good. |
