causes | What causes Harlequin ichthyosis ? | What causes harlequin ichthyosis? Harlequin ichthyosis is caused by mutations in the ABCA12 gene. This gene provides instructions for making a protein that is essential for the normal development of skin cells. This protein plays a major role in the transport of fats (lipids) in the outermost layer of skin (the epidermis). Some mutations in the ABCA12 gene prevent the cell from making any ABCA12 protein, while others lead to the production of an abnormally small version of the protein that cannot transport lipids properly. A loss of functional ABCA12 protein disrupts the normal development of the epidermis, resulting in the hard, thick scales characteristic of harlequin ichthyosis. |
inheritance | Is Harlequin ichthyosis inherited ? | How is harlequin ichthyosis inherited? Harlequin ichthyosis 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. |
exams and tests | How to diagnose Harlequin ichthyosis ? | Can harlequin ichthyosis be diagnosed before birth using amniocentesis or chorionic villus sampling? Yes, harlequin ichthyosis can be diagnosed before birth using either amniocentesis or chorionic villus sampling. Both of these procedures are used to obtain a sample of fetal DNA, which can be tested for mutations in the ABCA12 gene. The Genetic Testing Registry (GTR) provides information about the genetic tests for this condition. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a specific genetic test should contact a health care provider or a genetics professional. |
symptoms | What are the symptoms of Multiple epiphyseal dysplasia 4 ? | What are the signs and symptoms of Multiple epiphyseal dysplasia 4? The Human Phenotype Ontology provides the following list of signs and symptoms for Multiple epiphyseal dysplasia 4. 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 epiphysis morphology 90% Osteoarthritis 90% Arthralgia 50% Cleft palate 50% Clinodactyly of the 5th finger 50% Patellar aplasia 50% Scoliosis 50% Talipes 50% Hearing abnormality 7.5% Short stature 7.5% Autosomal recessive inheritance - Brachydactyly syndrome - Epiphyseal dysplasia - Flat capital femoral epiphysis - Hip dysplasia - Hypoplasia of the femoral head - Limited elbow flexion - Multiple epiphyseal dysplasia - Short metacarpal - Talipes equinovarus - 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) Dominant optic atrophy ? | Dominant optic atrophy (DOA) is an inherited optic nerve disorder characterized by degeneration of the optic nerves. It typically starts during the first decade of life. Affected people usually develop moderate visual loss and color vision defects. The severity varies and visual acuity can range from normal to legal blindness. About 20% of people with DOA have non-ocular features, such as sensorineural hearing loss; myopathy; peripheral neuropathy; multiple sclerosis-like illness; and spastic paraplegia (impaired function of the legs). These cases may be referred to as 'DOA plus.' DOA is inherited in an autosomal dominant manner and may be caused by a mutation in any of several genes, some of which have not been identified. There is currently no way to prevent or cure DOA, but affected people may benefit from low vision aids. |
inheritance | Is Dominant optic atrophy inherited ? | How is dominant optic atrophy inherited? Dominant optic atrophy (DOA) is inherited in an autosomal dominant manner. This means that having a change (mutation) in only one copy of the responsible gene in each cell is enough to cause features of the condition. In some cases, an affected person inherits the mutated gene from a parent. In other cases, the mutation occurs for the first time in an affected person and is not inherited from a parent (a de novo mutation). When a person with a mutation that causes DOA has children, each child has a 50% (1 in 2) chance to inherit the mutation. While a mutation responsible for DOA can cause the condition, not all people with a mutation will develop DOA. This means that DOA has reduced penetrance. There are likely to be other genetic and environmental factors that influence whether a person with a mutation will develop features of DOA. Additionally, not all people who do develop features will be affected the same way, and severity can vary - even within families. This phenomenon is known as variable expressivity. People with questions about genetic risks or genetic testing for themselves or family members are encouraged to speak with a genetics professional. |
treatment | What are the treatments for Dominant optic atrophy ? | How might dominant optic atrophy be treated? There is currently no cure for dominant optic atrophy (DOA). Management generally consists of regular eye exams, including measurement of visual acuity, color vision, visual fields and optical coherence tomography (OCT). Currently there is no specific treatment, but low-vision aids in individuals with severely decreased visual acuity can be helpful. A preliminary study published in February 2013 found that several individuals with specific OPA1 mutations who underwent idebenone therapy (which has been used to treat some cases of Leber hereditary optic neuropathy) experienced some improvement of visual function. However, more thorough research is necessary to confirm these findings. Acupuncture is also being studied as a potential treatment. Avoiding tobacco and alcohol intake and certain medications (antibiotics, antivirals), which can interfere with mitochondrial metabolism, may help to slow the progression. Cochlear implants have been shown to markedly improve hearing in individuals with sensorineural hearing loss. |
information | What is (are) Buschke Ollendorff syndrome ? | Buschke Ollendorff syndrome (BOS) is a genetic condition of the connective tissue. Common signs and symptoms include non-cancerous skin lumps and spots of increased bone density (which can be seen on X-ray). Some people with BOS have both skin and bone symptoms, while others have one or the other. Individual cases of BOS have occurred in association with joint pain, hearing disorders (e.g., otosclerosis), congenital spinal stenosis, craniosynostosis, and nail patella syndrome. Symptoms of BOS may begin at any age, but most often present before age 20. BOS is caused by mutations in the LEMD3 gene. The mutation results in a loss of protein (also named LEMD3) that results in the excessive formation of bone tissue. It is not clear how the LEMD3 mutations cause the skin lumps or other features of BOS. BOS is inherited in an autosomal dominant fashion. Affected members of the same family can have very different symptoms. |
symptoms | What are the symptoms of Buschke Ollendorff syndrome ? | What are the signs and symptoms of Buschke Ollendorff syndrome? Buschke Ollendorff syndrome (BOS) is an association of connective tissue nevi and osteopoikilosis (small, round areas of increased bone density). The nevi are typically present on the trunk, in the sacrolumbar region (lower back and sacrum), and on the extremities (arms and legs). Occasionally, they may be on the head. The nevi are usually nontender and firm, and are typically first noticeable as slightly elevated and flattened yellowish bumps, grouped together and forming plaques that may be several centimeters in diameter. The plaques are typically of irregular shape. They are usually numerous, painless, and develop over several years. The osteopoikilosis typically occurs in the long bones, wrist, foot, ankle, pelvis, and scapula. They are harmless and usually found by chance when radiographs are taken for other purposes, although pain and limited joint mobility have been reported in some individuals. In some individuals, only skin or bone manifestations may be present. Other signs and symptoms of BOS may include nasolacrimal duct obstruction, amblyopia ("lazy eye"), strabismus, benign lymphoid hyperplasia, hypopigmentation (abnormally light skin), and short stature. Congenital spinal stenosis (narrowing of the spine), disc herniation, clubfoot deformity, and nerve root compression may be present. Otosclerosis (abnormal growth of bone in the middle ear) with or without hearing loss may occur, but is rare. The Human Phenotype Ontology provides the following list of signs and symptoms for Buschke Ollendorff syndrome. 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.

inheritance | Is Buschke Ollendorff syndrome inherited ? | How is Buschke Ollendorff syndrome inherited? Buschke Ollendorff syndrome (BOS) is caused by mutations in the LEMD3 gene and is inherited in an autosomal dominant manner. This means that only one changed (mutated) copy of the gene in each cell is sufficient for a person to be affected by the condition. An affected individual may have inherited a mutated copy of the LEMD3 gene from an affected parent, or they may have been born with a new (de novo) mutation. There is a 50% (1 in 2) chance for each child of an affected individual to inherit the mutated gene, and a 50% chance for each child to not inherit the mutated gene. It has been proposed that the inheritance of BOS shows incomplete penetrance. Penetrance refers to the proportion of people with a particular genetic change (such as a mutation in a specific gene) who exhibit signs and symptoms of a genetic disorder. If some people with the mutation do not develop features of the disorder, the condition is said to have reduced (or incomplete) penetrance. Reduced penetrance probably results from a combination of genetic, environmental, and lifestyle factors, many of which are unknown. This phenomenon can make it challenging for genetics professionals to interpret a persons family medical history and predict the risk of passing a genetic condition to future generations. This means that not all individuals who have a new or inherited mutation in the LEMD3 gene will necessarily develop signs and symptoms of BOS. |
exams and tests | How to diagnose Buschke Ollendorff syndrome ? | Is genetic testing available for Buschke Ollendorff syndrome? Yes. GeneTests lists the names of laboratories that are performing genetic testing for Buschke Ollendorff syndrome. To view the contact information for the clinical laboratories conducting testing, click here. Please note: Most of the laboratories listed through GeneTests do not accept direct contact from patients and their families; therefore, if you are interested in learning more, you will need to work with a health care provider or a genetics professional. |
treatment | What are the treatments for Buschke Ollendorff syndrome ? | How might Buschke Ollendorff syndrome be treated? There is currently no cure for BOS. Surgical removal of lesions on or under the skin may be done for cosmetic purposes. In some patients, surgical treatment of deafness may be possible. Surgery might also be necessary for some of the signs or symptoms associated with BOS. Osteopoikilosis is typically asymptomatic, but about 15-20% of individuals experience pain and joint effusions (fluid build-up). Usually, no special restrictions in activity are required for individuals with BOS.[3150] |
information | What is (are) Cicatricial pemphigoid ? | Cicatricial pemphigoid is a rare, chronic, blistering and scarring disease that affects the oral and ocular mucosa. Other mucosal sites that might be affected include the nasopharnyx, larynx, genitalia, rectum, and esophagus. The condition usually begins in late adulthood (e.g. 50's or 60's), affects more women than men, and has a variable prognosis. Scarring of the affected mucosa of the eye may lead to blindness and tends to be the most feared complication. A combination of environmental and genetic factors appear to play a role in the susceptibility of developing cicatricial pemphigoid. Although the specific causes of this condition have not been identified, it is considered an autoimmune disease that is characterized by the production of autoantibodies against basement membrane zone antigens such as BP180, BP230, and laminin 5. Treatment is dependent on the person's specific symptoms. |

information | What is (are) Chromosome 16p13.3 deletion syndrome ? | Chromosome 16p13.3 deletion syndrome is a chromosome abnormality that can affect many parts of the body. People with this condition are missing a small piece (deletion) of chromosome 16 at a location designated p13.3. Although once thought to be a severe form of Rubinstein-Taybi syndrome, it is now emerging as a unique syndrome. Signs and symptoms may include failure to thrive, hypotonia (reduced muscle tone), short stature, microcephaly (unusually small head), characteristic facial features, mild to moderate intellectual disability, serious organ anomalies (i.e. heart and/or kidney problems), and vulnerability to infections. 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 has 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. To learn more about chromosomal anomalies in general, please visit our GARD webpage on Chromosome Disorders. |

information | What is (are) Castleman disease ? | Castleman disease (CD) is a rare condition that affects the lymph nodes and related tissues. There are two main forms: unicentric CD and multicentric CD. Unicentric CD is a "localized" condition that is generally confined to a single set of lymph nodes, while multicentric CD is a "systemic" disease that affects multiple sets of lymph nodes and other tissues throughout the body. The exact underlying cause of CD is currently unknown; however, it is thought to occur sporadically in people with no family history of the condition. Treatment varies based on the form of the condition, the severity of symptoms and whether or not the affected person also has an HIV and/or human herpes virus type 8 (HHV-8) infection. For more specific information about each form of CD, please visit GARD's unicentric Castleman disease and multicentric Castleman disease pages. |
causes | What causes Castleman disease ? | What causes Castleman disease? The exact underlying cause of Castleman disease (CD) is poorly understood. However, some scientists suspect that an increased production of interleukin-6 (IL-6) by the immune system may contribute to the development of CD. IL-6 is a substance normally produced by cells within the lymph nodes that helps coordinate the immune response to infection. Increased production of IL-6 may result in an overgrowth of lymphatic cells, leading to many of the signs and symptoms of CD. It has also been found that a virus called human herpes virus type 8 (also known as HHV-8, Kaposi's sarcoma-associated herpesvirus, or KSHV) is present in many people with multicentric CD, specifically. HHV-8 is found in nearly all people who are HIV-positive and develop multicentric CD, and in up to 60% of affected people without HIV. The HHV-8 virus may possibly cause multicentric CD by making its own IL-6. |

information | What is (are) Facioscapulohumeral muscular dystrophy ? | Facioscapulohumeral muscular dystrophy is a disorder characterized by muscle weakness and wasting (atrophy). This condition gets its name from the areas of the body that are affected most often: muscles in the face (facio-), around the shoulder blades (scapulo-), and in the upper arms (humeral). The signs and symptoms of facioscapulohumeral muscular dystrophy usually appear in adolescence. However, the onset and severity of the condition varies widely. Facioscapulohumeral muscular dystrophy results from a deletion of genetic material from a region of DNA known as D4Z4. This region is located near one end of chromosome 4. It is inherited in an autosomal dominant pattern. |

information | What is (are) Hereditary hemorrhagic telangiectasia ? | Hereditary hemorrhagic telangiectasia (HHT) is an inherited disorder of the blood vessels that can cause excessive bleeding. People with this condition can develop abnormal blood vessels called arteriovenous malformations (AVMs) in several areas of the body. If they are on the skin, they are called telangiectasias. The AVMs can also develop in other parts of the body, such as the brain, lungs, liver, or intestines. HHT is caused by mutations in the ACVRL1, ENG, and SMAD4 genes. It is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. There is no cure for HHT. Treatment is symptomatic and supportive, with a focus on controlling bleeding, either through surgery or medication. |

treatment | What are the treatments for Hereditary hemorrhagic telangiectasia ? | Can hereditary hemorrhagic telangiectasia (HHT) be treated? Yes. Although there is not yet a way to prevent the telangiectases or AVMs associated with HHT, most can be treated once they occur. Management includes surveillance for undiagnosed AVMs and treatment for identified complications such as nosebleeds, gastrointestinal bleeding, anemia, pulmonary AVMs, cerebral AVMs, and hepatic AVMs. Treatment of nosebleeds with humidification and nasal lubricants, laser ablation, septal dermoplasty, or estrogen-progesterone therapy can prevent anemia and allow individuals with HHT to pursue normal activities. Individuals with GI bleeding are treated with iron therapy to maintain hemoglobin concentration; endoscopic application of a heater probe, bicap, or laser; surgical removal of bleeding sites; and estrogen-progesterone therapy. Iron replacement and red blood cell transfusions are used to treat anemia. Pulmonary AVMs with feeding vessels that exceed 3.0 mm in diameter require occlusion. Cerebral AVMs greater than 1.0 cm in diameter are treated by surgery, embolotherapy, and/or stereotactic radiosurgery. The treatment of choice for hepatic AVMs is liver transplantation. Blood-thinning medications (anticoagulants) and anti-inflammatory agents should be avoided. Some patients may need to take antibiotics during simple dental or surgical procedures. Individual patients and their doctors should make decisions regarding these measures, as necessary. Surveillance includes annual evaluations for anemia and neurologic conditions and re-evaluation for pulmonary AVMs every one to two years during childhood and every five years thereafter. Women with HHT considering pregnancy are screened and treated for pulmonary AVMs; if pulmonary AVMs are discovered during pregnancy, they are treated during the second trimester. |

information | What is (are) Progressive pseudorheumatoid arthropathy of childhood ? | Progressive pseudorheumatoid arthropathy of childhood (PPAC) is a disorder of bone and cartilage that affects many joints. Major signs and symptoms include stiff joints (contractures), short stature, and widening of the ends of the finger and toe bones as well as other tubular bones. PPAC may initially be mistaken for juvenile rheumatoid arthritis, however people with this condition do not have the laboratory test results of juvenile rheumatoid arthritis. PPAC is caused by a mutation in the WISP3 gene and is inherited in an autosomal recessive pattern. People with PPAC typically need joint replacement surgery at an early age. Other forms of spondyloepiphyseal dysplasia tarda include: X-linked spondyloepiphyseal dysplasia tarda Autosomal dominant spondyloepiphyseal dysplasia tarda Spondyloepiphyseal dysplasia tarda Toledo type |

information | What is (are) Congenital central hypoventilation syndrome ? | Congenital central hypoventilation syndrome (CCHS) is a disorder of the autonomic nervous system that affects breathing. It causes a person to hypoventilate (especially during sleep), resulting in a shortage of oxygen and a buildup of carbon dioxide in the blood. Symptoms usually begin shortly after birth. Affected infants hypoventilate upon falling asleep and exhibit a bluish appearance of the skin or lips (cyanosis). Other features may include difficulty regulating heart rate and blood pressure; decreased perception of pain; low body temperature; sporadic profuse sweating; Hirschsprung disease; constipation; learning difficulties; eye abnormalities; and a characteristic facial appearance (having a short, wide, somewhat flattened face). CCHS is caused by a mutation in the PHOX2B gene and is inherited in an autosomal dominant manner. However, over 90% of cases are due to a new mutation in the affected person and are not inherited from a parent. Treatment typically includes mechanical ventilation or use of a diaphragm pacemaker. |

inheritance | Is Congenital central hypoventilation syndrome inherited ? | How is congenital central hypoventilation syndrome inherited? Congenital central hypoventilation syndrome (CCHS) is inherited in an autosomal dominant manner. This means that having a change (mutation) in only one copy of the responsible gene in each cell is enough to cause features of the condition. The genetics of CCHS can be complex. Most people with CCHS have a new (de novo) mutation in the responsible gene (the PHOX2B gene). De novo mutations occur for the first time in the affected person and are not inherited from a parent. Some people with CCHS have a parent with the condition, and inherit the mutation from that parent. In some cases, an asymptomatic parent of a person with symptoms has a PHOX2B mutation in some of their germ cells (egg or sperm cells, not body cells). This is called germline mosaicism. Some of these parents also have a PHOX2B mutation in some of their body cells. This is called somatic mosaicism. Germline mosaicism with or without somatic mosaicism is present in about 25% of asymptomatic parents of people with CCHS. Parents with mosaicism should have a comprehensive assessment to determine if any features of CCHS are present. It is also recommended that parents of a person with a presumed de novo mutation have genetic testing for the presence of the mutation, including testing that detects mosaicism at low levels. |
information | What is (are) Familial progressive cardiac conduction defect ? | Familial progressive cardiac conduction defect (PCCD) is a is a cardiac (heart) conduction disorder that may progress to complete heart block. Affected people may not have any symptoms, or the condition may cause shortness of breath, dizziness, fainting, abdominal pain, heart failure, or sudden death. Mutations in several genes, including the SCN5A, SCN1B and TRPM4 genes, can cause PCCD. Several other genes may be the cause when PCCD occurs with congenital heart disease. Familial PCCD is usually inherited in an autosomal dominant manner. However, not all people that have the mutated gene will have the condition; in those that do, symptoms and severity can vary (known as reduced penetrance and variable expressivity). Autosomal recessive inheritance and sporadic cases have been reported, but are rare. Treatment includes implantation of a pacemaker. |

information | What is (are) Lymphomatoid papulosis ? | Lymphomatoid papulosis is a skin disorder that is characterized by crops of self healing skin lesions that look cancerous under the microscope but are actually benign (non-cancerous). Lesions contain unusual cells that are similar to those found in some lymphomas (cancers of the lymphatic system). |
symptoms | What are the symptoms of Lymphomatoid papulosis ? | What are the early signs of lymphomatoid papulosis? Patients may present with multiple skin papules (raised bumps) that can occur anywhere on the body but most often on the chest, stomach, back, arms, and legs. The papules appear in crops and may be mildly itchy. They may develop into blood or pus-filled blisters that break and form a crusty sore before healing completely. Lesions tend to spontaneously heal with or without scarring within 2-8 weeks of appearing. |
causes | What causes Lymphomatoid papulosis ? | What causes lymphomatoid papulosis? The cause of lymphomatoid papulosis is unknown, but it is associated with a proliferation of atypical T-cells. T-cells are specific white blood cells involved in immune responses. |
treatment | What are the treatments for Lymphomatoid papulosis ? | How might lymphomatoid papulosis be treated? Localized mildly itchy skin lesions may be treated with mid- to high-potency topical steroids to hasten healing, or with more aggressive topical therapies (e.g.,phototherapy) to suppress the disease and the possibility of progression to lymphoma. Low-dose weekly methotrexate has been used to suppress the condition with some success, however the treatment effects are not lasting. Oral psoralen plus UVA phototherapy may also effectively treat and suppresses the disease. A few reports have found that following treatments may also help with disease suppression: Topical carmustine Topical nitrogen mustard Topical MTX Topical imiquimod cream Intralesional interferon Low-dose cyclophosphamide Chlorambucil Medium-dose UVA-1 therapy Excimer laser therapy Dapsone |
information | What is (are) Senior Loken Syndrome ? | Senior Loken syndrome is a rare disorder characterized by the combination of two specific features: a kidney condition called nephronophthisis and an eye condition known as Leber congenital amaurosis. It can be caused by mutations in one of at least six genes. The proteins produced from these genes are known or suspected to play roles in cell structures called cilia. These microscopic, finger-like projections stick out on the surface of cells and are involved in signaling pathways that transmit information between cells. Cilia are important for the structure and function of many types of cells, including certain cells in the kidneys. They are also necessary for the perception of sensory input (such as vision, hearing, and smell). Senior Loken syndrome is inherited in an autosomal recessive pattern. |

information | What is (are) Lymphocytic colitis ? | Lymphocytic colitis is form of microscopic colitis, a condition that is characterized by inflammation of the colon (large intestines). As the name suggests, microscopic colitis can only be diagnosed by examining a small sample of colon tissue under a microscope. In lymphocytic colitis, specifically, the tissues and lining of the colon are of normal thickness, but an increase in the number of lymphocytes (a type of white blood cell) is observed. Signs and symptoms of the condition may include chronic, watery diarrhea; abdominal pain, cramping, and bloating; weight loss; nausea; dehydration; and/or fecal incontinence. The underlying cause of lymphocytic colitis is currently unknown; however, scientists suspect that autoimmune conditions, medications, infections, genetic factors, and/or bile acid malabsorption may contribute to the development of the condition. Treatment is based on the signs and symptoms present in each person and may include certain medications, dietary modifications, and in rare cases, surgery. |

information | What is (are) Gangliocytoma ? | Gangliocytoma is a rare type of central nervous system (CNS) tumor made up of mature neurons. Gangliocytomas may occur in all age groups but most often occur in people between the ages of 10 and 30. The most common site is the temporal lobe of the brain, but they can arise anywhere in the CNS including the cerebellum, brainstem, floor of the third ventricle, and spinal cord. They are among the most frequent tumors associated with epilepsy. Signs and symptoms may depend on the tumor's location and may include seizures (most commonly); increased brain pressure; endocrine disorders; and focal symptoms. Gangliocytomas are generally slow-growing and usually do not become malignant. Treatment involves surgical removal of the tumor. Click here to view a separate page about dysplastic gangliocytoma of the cerebellum (also called Lhermitte-Duclose disease). |
symptoms | What are the symptoms of Gangliocytoma ? | What are the signs and symptoms of gangliocytomas? Signs and symptoms caused by the presence of a gangliocytoma can vary depending on the tumor's location. Seizures are the most common symptom. Other symptoms may include increased brain pressure, endocrine disorders, and focal symptoms. Gangliocytomas can also be asymptomatic (cause no symptoms) and may be diagnosed incidentally on imaging studies. |
information | What is (are) Kimura disease ? | Kimura disease is a rare, benign, chronic disorder that causes inflammation of tissue (nodules) under the skin of the head or neck. These nodules tend to recur despite treatment. The cause of this condition is unknown, but may be due to an immune response. |
treatment | What are the treatments for Kimura disease ? | How might Kimura disease be treated? For individuals with symptoms caused by Kimura disease, surgery to remove the nodules is the treatment of choice; however, the nodules often reappear after surgery. Steroids (such as prednisone), taken by mouth or via an injection in the skin, can shrink the nodules but rarely result in a cure. Other, less common, treatments include oral pentoxifylline, medication that supresses the immune system (such as cyclosporine), radiotherapy, and a combination of all trans-retinoic acid and prednisone. It is important to consult with your healthcare provider before taking any medication. |
information | What is (are) Dermatitis herpetiformis ? | Dermatitis herpetiformis is a rare, chronic, skin disorder characterized by groups of severely itchy blisters and raised skin lesions. These are more common on the knees, elbows, buttocks and shoulder blades. The slow onset of symptoms usually begins during adulthood, but children can also be affected. Other symptoms may include fluid-filled sores; red lesions that resemble hives; and itchiness, redness and burning. The exact cause of this disease is not known, but it is frequently associated with the inability to digest gluten. People with this disease are typically treated with the drug dapsone. |

treatment | What are the treatments for Dermatitis herpetiformis ? | How might dermatitis herpetiformis be treated? The antibiotic dapsone is extremely effective in treating this condition. Symptomatic improvement may occur in as little as several hours after the first dose. However, dapsone may cause serious side effects and requires regular monitoring by a physician. When this medication is used to relieve the symptoms of dermatitis herpetiformis, it should be taken in the smallest effective dose and for the shortest period possible. In some cases, immunosuppressive medications may be used. These medications do not appear to be as effective. A strict gluten-free diet is also recommended to help control the disease. Following this diet may eliminate the need for medications and prevent later complications. |
information | What is (are) Baller-Gerold syndrome ? | Baller-Gerold syndrome is a rare condition characterized by the premature fusion of certain skull bones (craniosynostosis) and abnormalities of bones in the arms and hands, sometimes referred to as radial ray anomalies. Many cases of Baller-Gerold syndrome are caused by mutations in the RECQL4 gene. These cases are inherited in an autosomal recessive manner. In a few reported cases, the characteristic features of Baller-Gerold syndrome have been associated with prenatal exposure to a drug called sodium valproate which is used to treat epilepsy and certain psychiatric disorders. Treatment may include surgery for treatment of craniosynostosis or reconstruction of the index finger to functional thumb. The symptoms of Baller-Gerold syndrome overlap with features of Rothmund-Thomson syndrome and RAPADILINO syndrome which are also caused by the RECQL4 gene. Researchers are trying to determine if these conditions are separate disorders or part of a single syndrome with overlapping signs and symptoms. |
symptoms | What are the symptoms of Baller-Gerold syndrome ? | What are the signs and symptoms of Baller-Gerold syndrome? Many people with Baller-Gerold syndrome have prematurely fused skull bones along the coronal suture, the growth line that goes over the head from ear to ear. Other parts of the skull may be malformed as well. These changes result in an abnormally shaped head, a prominent forehead, and bulging eyes with shallow eye sockets (ocular proptosis). Other distinctive facial features can include widely spaced eyes (hypertelorism), a small mouth, and a saddle-shaped or underdeveloped nose. Bone abnormalities in the hands include missing fingers (oligodactyly) and malformed or absent thumbs. Partial or complete absence of bones in the forearm is also common. Together, these hand and arm abnormalities are called radial ray malformations. People with Baller-Gerold syndrome may have a variety of additional signs and symptoms including slow growth beginning in infancy, small stature, and malformed or missing kneecaps (patellae). A skin rash often appears on the arms and legs a few months after birth. This rash spreads over time, causing patchy changes in skin coloring, areas of skin tissue degeneration, and small clusters of enlarged blood vessels just under the skin. These chronic skin problems are collectively known as poikiloderma. The Human Phenotype Ontology provides the following list of signs and symptoms for Baller-Gerold syndrome.

information | What is (are) 22q11.2 duplication syndrome ? | 22q11.2 duplication syndrome is a condition caused by an extra copy of a small piece of chromosome 22 which contains about 30 to 40 genes. The features of this condition vary widely, even among members of the same family (intrafamilial variability). Affected individuals may have intellectual or learning disability, developmental delay, slow growth leading to short stature, and weak muscle tone (hypotonia). Many people with the condition have no apparent physical or intellectual disabilities. It is inherited in an autosomal dominant manner, with about 70% genes of affected individuals inheriting the condition from a parent. In other cases it occurs as a de novo mutation (new genetic change) in an individual; however, individuals with a de novo mutation can can pass the duplication to their children. Researchers are working to determine which duplicated genes may contribute to the developmental delay and other problems that sometimes affect people with this condition. Duplication is not detectable by karyotype and most of the people with 22q11.2 duplication syndrome are identified by a special technique known as chromosomal microarray. Treatment depends on the symptoms and includes an individualized educational program. Read more out chromosome 22. |

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) Triploidy ? | Triploidy is a chromosome abnormality that occurs when there is an extra set of chromosomes present in each cell. Most pregnancies affected by triploidy are lost through early miscarriage. However, reports exist of some affected babies living up to five months. Those that survive are often mosaic. The signs and symptoms associated with triploidy vary but may include a variety of birth defects and an unusually small size. This condition does not run in families and is not associated with maternal or paternal age. Treatment is based on the signs and symptoms present in each person. |

information | What is (are) Erythropoietic protoporphyria ? | Erythropoietic protoporphyria is a type of porphyria. Porphyrias are caused by an abnormality in the heme production process. Heme is essential in enabling our blood cells to carry oxygen and in breaking down chemical compounds in the liver. Erythropoietic protoporphyria is caused by impaired activity of ferrocheletase (FECH), an important enzyme in heme production. This results in the build-up of protoporphyrin in the bone marrow, red blood cells, blood plasma, skin, and eventually liver. Build up of protoporphyrin can cause extreme sensitivity to sunlight, liver damage, abdominal pain, gallstones, and enlargement of the spleen. |

causes | What causes Erythropoietic protoporphyria ? | What is the genetic basis of erythropoietic protoporphyria? Erythropoietic protoporphyria is caused by mutations in the FECH gene. |
inheritance | Is Erythropoietic protoporphyria inherited ? | How is erythropoietic protoporphyria (EPP) inherited? EPP is inherited in an autosomal recessive manner. In most cases, affected individuals have one severe (loss-of-function) mutation that is inherited from one parent, and another weak (low-expression) mutation that is inherited from the other parent. In a small number of cases, an affected individual has two loss-of-function mutations. When 2 carriers of an autosomal recessive condition have children, each child has a: 25% (1 in 4) chance to be affected 50% (1 in 2) chance to be an unaffected carrier like each parent 25% (1 in 4) chance to be unaffected and not be a carrier |
information | What is (are) Fine-Lubinsky syndrome ? | Fine-Lubinsky syndrome (FLS) is a very rare syndrome that affects various parts of the body. Signs and symptoms can vary and may include brachycephaly or plagiocephaly; structural brain abnormalities; abnormal EEG; intellectual disability; deafness; eye conditions (cataracts or glaucoma); distinctive facial features; and body asymmetry. The underlying cause of FLS remains unknown. Almost all cases have been sporadic (occurring in people with no family history of FLS) with the exception of 2 affected siblings, suggesting it was inherited in an autosomal recessive manner. |
symptoms | What are the symptoms of Fine-Lubinsky syndrome ? | What are the signs and symptoms of Fine-Lubinsky syndrome? The signs and symptoms known to occur in people with Fine-Lubinsky syndrome (FLS) are based on reports of the few people who have been diagnosed and described in the medical literature. Numerous features have been reported and many of them vary among affected people. The key signs for diagnosis may include: non-synostotic brachycephaly or plagiocephaly (a deformity of the skull that is not due to bone fusion) structural brain anomalies abnormal electroencephalogram (EEG) intellectual disability deafness ocular (eye) abnormalities (cataracts or glaucoma) distinctive facial features (including a high/wide forehead; shallow eye orbits; a flat/round face; low-set, posteriorly-rotated ears; and an abnormally small mouth) body asymmetry, which may be present at birth (congenital) The Human Phenotype Ontology provides the following list of signs and symptoms for Fine-Lubinsky syndrome.

causes | What causes Fine-Lubinsky syndrome ? | What causes Fine-Lubinsky syndrome? The cause of Fine-Lubinsky syndrome remains unknown. With the exception of one family report of an affected brother and sister (suggesting an autosomal recessive inheritance pattern), all other cases have been sporadic (occurring in people with no family history of FLS). Additional reports are needed to identify a possible genetic cause of FLS. While karyotypes (pictures of chromosomes) were reportedly normal in affected people, the presence of a very small chromosomal rearrangement (too small to detect with a karyotype) as a possible cause for FLS has not been ruled out. |
inheritance | Is Fine-Lubinsky syndrome inherited ? | How is Fine-Lubinsky syndrome inherited? Almost all people reported to have FineLubinsky syndrome (FLS) have been the only affected people in their families (these cases were sporadic). There has been one report of an affected brother and sister with unaffected parents, suggesting autosomal recessive inheritance. Additional reports are needed to identify a possible genetic cause for the condition. Parents of a child with FLS should be aware that if the condition is inherited in an autosomal recessive manner, each of their children has a 25% (1 in 4) risk to be affected. Although karyotypes (pictures of chromosomes) have been reported as normal in affected people, the presence of a very small chromosomal rearrangement has not been excluded as a possible cause of FLS. |
exams and tests | How to diagnose Fine-Lubinsky syndrome ? | How is Fine-Lubinsky syndrome diagnosed? In 2009, Corona-Rivera et. al reviewed the signs and symptoms reported in people diagnosed with Fine-Lubinsky syndrome (FLS). They identified key signs for diagnosis as: non-synostotic (without synostosis) brachycephaly (short or broad head) or plagiocephaly (flattening of the head); structural brain anomalies; abnormal EEG; intellectual disability; deafness; ocular (eye) abnormalities including cataracts or glaucoma; distinctive facial features involving high/wide forehead, shallow orbits, flat/round face, low-set posteriorly rotated ears, and microstomia (small mouth); and body asymmetry. |

information | What is (are) Hypoaldosteronism ? | Hypoaldosteronism is a condition characterized by the shortage (deficiency) or impaired function of a hormone called aldosterone. Hypoaldosteronism may be described as hyporeninemic or hyperreninemic depending on renin levels. Hyporeninemic hypoaldosteronism occurs when there is decreased production of aldosterone due to decreased production of renin . Affected individuals typically have kidney (renal) disease due to various conditions, such as diabetes, interstitial nephritis, or multiple myeloma. Hyperreninemic hypoaldosteronism occurs when there is a problem with the production of aldosterone, but renin is produced normally by the kidneys. Common causes of this form of hypoaldosteronism are medications (ACE inhibitors), lead poisoning, severe illness, and aldosterone enzyme defects. |
treatment | What are the treatments for Hypoaldosteronism ? | How might hypoaldosteronism be treated? Treatment for hypoaldosteronism depends on the underlying condition. Affected individuals are often advised to follow a low-potassium diet with liberal sodium intake. People with hypoaldosteronism should typically avoid ACE inhibitors and potassium-sparing diuretics. Individuals with hypoaldosteronism and a deficiency of adrenal glucocorticoid hormones are usually given fludrocortisone. People with hyporeninemic hypoaldosteronism are frequently given furosemide to correct hyperkalemia. |
information | What is (are) LCHAD deficiency ? | LCHAD deficiency, or long-chain 3-hydroxyacyl-CoA dehydrogenase deficiency, is a mitochondrial condition that prevents the body from converting certain fats to energy, particularly during periods without food (fasting). Signs and symptoms typically appear during infancy or early childhood and can include feeding difficulties, lack of energy, low blood sugar (hypoglycemia), weak muscle tone (hypotonia), liver problems, and abnormalities in the retina. Later in childhood, people with this condition may experience muscle pain, breakdown of muscle tissue, and peripheral neuropathy. Individuals with LCHAD deficiency are also at risk for serious heart problems, breathing difficulties, coma, and sudden death. This condition is inherited in an autosomal recessive pattern and is caused by mutations in the HADHA gene.[OMIM] |

information | What is (are) Myelofibrosis ? | Myelofibrosis is a disorder of the bone marrow, in which the marrow is replaced by fibrous (scar) tissue. Scarring of the bone marrow causes anemia, which can lead to fatigue and weakness, as well as pooling of the blood in abnormal sites like the liver and spleen, causing these organs to swell. Although myelofibrosis can occur at any age, it typically develops after the age of 50. In most cases, myelofibrosis gets progressively worse. Treatment is aimed at relieving signs and symptoms and may include medications, blood transfusions, chemotherapy, radiation therapy and surgery. |

information | What is (are) 22q13.3 deletion syndrome ? | 22q13.3 deletion syndrome, also known as Phelan-McDermid syndrome, is a chromosome abnormality caused by the loss (deletion) of a small piece of chromosome 22. The deletion occurs near the end of the long arm (or q arm) at a location designated as q13.3. The signs and symptoms of this condition vary widely from person to person. Common symptoms include low muscle tone (hypotonia), intellectual disability, delayed or absent speech, abnormal growth, tendency to overheat, large hands, and abnormal toenails. Affected individuals may have characteristic behaviors, such as mouthing or chewing on non-food items, decreased perception of pain, and autistic-like behaviors. The loss of a particular gene on chromosome 22, called the SHANK3 gene, is likely responsible for many of the signs and symptoms of 22q13.3 deletion syndrome. Additional genes within the deleted region probably contribute to the variable features of the syndrome. |

information | What is (are) Cluttering ? | Cluttering is a disorder that affects the way a person speaks. It is characterized by a rapid speaking rate and inability to maintain normally expected sound, syllable, phrase, and pausing patterns while speaking. Other symptoms may include stuttering; language or phonological errors (problems organizing sounds); and attention deficits. The disorder seems to result from disorganized speech planning, talking too fast or in spurts, or simply being unsure of what one wants to say. Therapy generally focuses on the symptoms present in each individual and may include slowing the rate of speech and clearly producing speech sounds (articulating). Articulation and language problems are often reduced if the affected individual can achieve a slower rate of speech. |
