What is (are) Sjogren syndrome ? | Sjgren syndrome is an autoimmune disorder in which immune cells attack and destroy the glands that produce tears and saliva. Sjgren syndrome is also associated with rheumatic disorders such as rheumatoid arthritis or systemic lupus erythematosus. The hallmark symptoms of the disorder are dry mouth and dry eyes. In addition, Sjogren syndrome may cause skin, nose, and vaginal dryness, and may affect other organs of the body including the kidneys, blood vessels, lungs, liver, pancreas, and brain. Treatment is symptomatic and supportive and may include moisture replacement therapies, nonsteroidal anti-inflammatory drugs and, in severe cases, corticosteroids or immunosuppressive drugs. | |

In these cases, the sign or symptom may be rare or common. | |
What causes Sjogren syndrome ? | What causes Sjogren syndrome? Sjogren syndrome likely results from a combination of genetic and environmental factors (multifactorial). Several different genes appear to affect the risk of developing the condition, however, specific genes have yet to be confirmed. Simply having one of these genes does not cause a person to develop the disease; some sort of trigger is also needed. That trigger may be a viral or bacterial infection. The genetic variations that increase susceptibility may reduce the body's ability to turn off the immune response when it is no longer needed. The possibility that the endocrine and nervous systems may play a role in the disease is also under investigation. | |
Is Sjogren syndrome inherited ? | Is Sjogren syndrome inherited? A genetic predisposition to Sjogren syndrome has been suggested. Familial clustering of different autoimmune diseases as well as co-association of multiple autoimmune diseases in individuals have frequently been reported. Some studies have shown up to 30% of people with Sjogren syndrome have relatives with autoimmune diseases. While the relatives of people with Sjogren syndrome are at an increased risk of developing autoimmune diseases in general, they are not necessarily more likely to develop Sjogren syndrome. | |
What is (are) Neuronal ceroid lipofuscinosis 7 ? | Neuronal ceroid lipofuscinosis 7 (CLN7-NCL) is a rare condition that affects the nervous system. Signs and symptoms of the condition generally develop in early childhood (average age 5 years) and may include loss of muscle coordination (ataxia), seizures that do not respond to medications, muscle twitches (myoclonus), visual impairment, and developmental regression (the loss of previously acquired skills). CLN7-NCL is caused by changes (mutations) in the MFSD8 gene and is inherited in an autosomal recessive manner. Treatment options are limited to therapies that can help relieve some of the symptoms. | |

What is (are) Calciphylaxis ? | Calciphylaxis is a disease in which blood vessels (veins and arteries) become blocked by a build-up of calcium in the walls of the vessels, preventing blood from flowing to the skin or internal organs. The lack of blood flow (ischemia) damages healthy tissue and causes it to die (necrosis). The most obvious and frequent symptom of calciphylaxis is damage to the skin, as ulcers can develop and become infected easily. Calciphylaxis can also affect fat tissue, internal organs, and skeletal muscle, causing infections, pain, and organ failure. These symptoms are often irreversible, and many individuals with calciphylaxis may not survive more than a few months after they are diagnosed due to infection that spreads throughout the body (sepsis), or organ failure. The exact cause of calciphylaxis is unknown. Treatments may include medications to reduce pain, antibiotics to treat infections, and various approaches to preventing the development or worsening of this condition. | |

What is (are) Lesch Nyhan syndrome ? | Lesch Nyhan syndrome is a condition characterized by neurological and behavioral abnormalities and the overproduction of uric acid in the body. It occurs almost exclusively in males. Signs and symptoms may include inflammatory arthritis (gout), kidney stones, bladder stones, and moderate cognitive disability. Nervous system and behavioral disturbances also occur, such as involuntary muscle movements and self injury (including biting and head banging). People with Lesch Nyhan syndrome usually cannot walk, require assistance sitting, and generally use a wheelchair. Lesch Nyhan syndrome is caused by changes (mutations) in the HPRT1 gene and is inherited in an X-linked recessive manner. Treatment is symptomatic and supportive. Affected people often do not survive past the first or second decade of life due to renal failure. | |

Is Lesch Nyhan syndrome inherited ? | How is Lesch Nyhan syndrome inherited? Lesch Nyhan syndrome is inherited in an X-linked recessive manner. A condition is X-linked if the changed (mutated) gene responsible for the condition is located on the X chromosome. The X chromosome is one of the two sex chromosomes; females have two X chromosomes, and males have one X and one Y chromosome. Females who have one mutated copy of the responsible gene (on one of their X chromosomes) usually do not have the condition and are referred to as carriers. This is because they still have a working copy of the responsible gene on their other X chromosome. Males with one mutated copy of the responsible gene have signs and symptoms of the condition (they are affected) because they do not have another X chromosome with a working copy of the gene. This is why X-linked recessive disorders, including Lesch Nyhan syndrome, occur much more frequently in males. Lesch Nyhan syndrome is caused by mutations in the HPRT1 gene. A female who is a carrier of Lesch Nyhan syndrome has a 50% chance of passing on the mutated HPRT1 gene in each pregnancy. This is because a carrier female will randomly pass on one of her X chromosome to each child. Sons who inherit the mutated gene will be affected, and daughters who inherit the mutated gene will be carriers. This means that with each pregnancy, a female who is a carrier has a: 50% (1 in 2) chance of having an unaffected son or daughter 25% (1 in 4) chance of having an affected son 25% chance of having a carrier daughter | |
What is (are) Acute febrile neutrophilic dermatosis ? | Acute febrile neutrophilic dermatosis - also known as Sweet syndrome - is a skin condition marked by fever, inflammation of the joints (arthritis), and painful skin lesions that appear mainly on the face, neck, back and arms. Although middle-aged women are most likely to develop this condition, it may also affect men, older adults and even infants. The exact cause of acute febrile neutrophilic dermatosis often isn't known. In some people, it's triggered by an infection, illness or certain medications. This condition can also occur with some types of cancer and other serious health problems. Most often, it isn't serious and will clear on its own in a few months. Healing is much more rapid, however, with treatment. | |
What are the symptoms of Acute febrile neutrophilic dermatosis ? | What are the signs and symptoms of Acute febrile neutrophilic dermatosis? The most obvious signs of acute febrile neutrophilic dermatosis are distinctive skin lesions that usually develop according to a specific pattern. Typically, a series of small red bumps appear suddenly on the back, neck, arms and face, often after a fever or upper respiratory infection. The bumps grow quickly in size, spreading into clusters called plaques that may be a centimeter in diameter or larger. The eruptions are tender or painful and may develop blisters, pustules or even ulcers. Lesions may persist for weeks to months and then disappear on their own, without medication. With medical treatment, the skin lesions may resolve in just a few days. Other signs and symptoms of acute febrile neutrophilic dermatosis may include: Moderate to high fever Pink eye (conjunctivitis) or sore eyes Tiredness Aching joints and headache Mouth ulcers The Human Phenotype Ontology provides the following list of signs and symptoms for Acute febrile neutrophilic dermatosis. If the information is available, the table below includes how often the symptom is seen in people with this condition.

What causes Acute febrile neutrophilic dermatosis ? | What causes acute febrile neutrophilic dermatosis? In many cases, the cause of acute febrile neutrophilic dermatosis is unknown (idiopathic). But sometimes, it can be a sign of an immune system response to one of the following: An upper respiratory tract infection, such as a chest infection or strep throat Blood disorders, especially acute myelogenous leukemia, a cancer of the blood and bone marrow Inflammatory bowel disease, such as ulcerative colitis or Crohn's disease Bowel or breast cancer Pregnancy Rheumatoid arthritis An injury at the site where the rash appears, such as an insect bite or needle prick Certain medications, including nonsteroidal anti-inflammatory drugs (NSAIDs) | |
What are the treatments for Acute febrile neutrophilic dermatosis ? | How might acute febrile neutrophilic dermatosis be treated? Left untreated, acute febrile neutrophilic dermatosis not associated with a more serious condition may disappear on its own within one to three months. Medications can improve skin lesions and associated symptoms in just two or three days, with the worst of the lesions disappearing within one to four weeks. Doctors usually prescribe systemic corticosteroids (prednisone or prednisolone) to treat this condition. These oral anti-inflammatory medications reduce redness, itching, swelling and allergic reactions. In the pediatric population, long-term use of corticosteroids can cause problems with linear growth, blood pressure, and blood glucose levels. Children may also have social sequelae associated with their use. Therefore, attempts are usually made to treat children with steroid-sparing drugs. Other treatment options include indomethacin, colchicine, potassium iodide, dapsone, cyclosporine, etretinate, pentoxifylline, clofazimine, doxycycline, metronidazole, isotretinoin, methotrexate, cyclophosphamide, chlorambucil, and interferon alpha, all of which have shown some success in the resolution of symtpoms. With or without treatment, the lesions rarely leave a mark or scar when they eventually disappear. Even after the lesions have resolved, treatment may continue, as recurrence of the condition is common. If an underlying cause can be identified, it should be treated (i.e. resection of solid tumors, treatment of infections, and discontinuation of causative medication). Successful therapy of the underlying disorder may promote resolution of acute febrile neutrophilic dermatosis and prevent recurrences. | |
What is (are) Birt-Hogg-Dube syndrome ? | Birt-Hogg-Dube syndrome (BHDS) is a rare, complex, genetic disorder with three main clinical findings: non-cancerous (benign) skin tumors; lung cysts and/or history of pneumothorax (collapsed lung); and various types of renal tumors. Fibrofolliculomas are a type of benign skin tumor specific to BHDS. They typically occur on the face, neck, and upper torso. Most people with BHDS also have multiple cysts in both lungs that can be seen on high-resolution chest CT scan. While these cysts usually do not cause any symptoms, they put people at increased risk for spontaneous pneumothorax. BHDS is caused by mutations in the FLCN gene. The condition is inherited in an autosomal dominant fashion. | |

What are the treatments for Birt-Hogg-Dube syndrome ? | How might lung cysts associated with Birt-Hogg-Dube syndrome be treated? At the time of diagnosis of Birt-Hogg-Dube (BHD) syndrome, a computed tomography (CT) scan, or high resolution CT scan if available, should be done to determine the number, location, and size of any cysts in the lungs. There is no recommended management of the lung cysts. Lung cysts related to BHD have not been associated with long-term disability or fatality. The main concern is that the cysts may increase the chance of developing a collapsed lung (pneumothorax). If an individual with BHD experiences any symptoms of a collapsed lung - such as chest pain, discomfort, or shortness of breath - they should immediately go to a physician for a chest x-ray or CT scan. Therapy of a collapsed lung depends on the symptoms, how long it has been present, and the extent of any underlying lung conditions. It is thought that collapsed lung can be prevented by avoiding scuba diving, piloting airplanes, and cigarette smoking. Individuals with BHD who have a history of multiple instances of collapsed lung or signs of lung disease are encouraged to see a lung specialist (pulmonologist). | |
What is (are) Dermal eccrine cylindroma ? | Cylindromas are non-cancerous (benign) tumors that develop from the skin. They most commonly occur on the head and neck and rarely become cancerous (malignant). An individual can develop one or many cylindromas; if a person develops only one, the cylindroma likely occurred by chance and typically is not inherited. They usually begin to form during mid-adulthood as a slow-growing, rubbery nodule that causes no symptoms. The development of multiple cylindromas can be hereditary and is inherited in an autosomal dominant manner; this condition is called familial cylindromatosis. Individuals with the inherited form begin to develop many, rounded nodules of various size shortly after puberty. The tumors grow very slowly and increase in number over time. | |

What is (are) Adenoameloblastoma ? | Adenoameloblastoma is a lesion that is often found in the upper jaw. Some consider it a non-cancerous tumor, others a hamartoma (tumor-like growth) or cyst. Often, an early sign of the lesion is painless swelling. These tumors are rarely found outside of the jaw. | |
What causes Adenoameloblastoma ? | What causes adenoameloblastoma? Currently the cause of adenoameloblastoma is not well understood. It may be associated with an interruption in tooth development. These legions tend to occur more commonly in young people (around 20 year-old), and most often in young women. Adenoameloblastomas in the front upper jaw are often associated with an impacted tooth. | |
What are the treatments for Adenoameloblastoma ? | How might adenoameloblastoma be treated? Treatment may require the removal of the legion as well as the surrounding tissues. Once the treatment is complete, recurrence of the legion is very rare. | |

What is (are) Congenital chloride diarrhea ? | Congenital chloride diarrhea is a condition characterized by large, watery stools containing an excess of chloride. Individuals have intrauterine (pre-birth) and lifelong diarrhea; infants with the condition are often premature. The excessive diarrhea causes electrolyte and water deficits, which in turn cause volume depletion, hyperreninemia (elevated levels of renin in the blood), hyperaldosteronism, renal potassium wasting, and sometimes nephropathy. Mutations in the SLC26A3 gene have been found to cause the condition. It is inherited in an autosomal recessive manner. Treatment generally focuses on the individual symptoms of the condition and typically includes taking oral supplements of sodium and potassium chloride. | |

What are the treatments for Congenital chloride diarrhea ? | How might congenital chloride diarrhea be treated? There is no cure for the underlying condition, so treatment mainly focuses on the symptoms. Studies have shown that early diagnosis and aggressive salt replacement therapy (replacing sodium and chloride, the 2 things that make up salt) are associated with normal growth and development, in addition to reduced mortality rates. In individuals with this condition, the goal is for the oral intake of chloride, sodium, and potassium to be greater than the amount lost through the feces (i.e., there must be a positive gastrointestinal balance) so that losses in sweat can be replaced. Replacement therapy with NaCl (sodium chloride) and KCl (potassium chloride) has been shown to be effective in children. One study showed that a medication called omeprazole, a proton-pump inhibitor, reduces electrolyte losses in individuals and thus promotes a positive gastrointestinal balance. However, this treatment does not reduce the need for careful monitoring of dietary intake, electrolyte concentrations, and urinary chloride loss. Another study discussed how butyrate could be effective in treating the condition, and that it is easily administered, useful in preventing severe dehydration episodes, and may be a promising approach for a long-term treatment. | |
What is (are) Growth hormone deficiency ? | Growth hormone deficiency is characterized by abnormally short height due to lack (or shortage) of growth hormone. It can be congenital (present at birth) or acquired. Most of the time, no single clear cause can be identified. Most cases are identified in children. Although it is uncommon, growth hormone deficiency may also be diagnosed in adults. Too little growth hormone can cause short stature in children, and changes in muscle mass, cholesterol levels, and bone strength in adults. In adolescents, puberty may be delayed or absent. Treatment involves growth hormone injections. | |
What is (are) Hypertryptophanemia ? | Hypertryptophanemia is a rare condition that likely occurs due to abnormalities in the body's ability to process the amino acid (a building block of proteins), tryptophan. People affected by this condition may experience intellectual disability and behavioral problems (i.e. periodic mood swings, exaggerated emotional responses and abnormal sexual behavior). The underlying genetic cause of hypertryptophanemia is currently unknown; however, it appears to be inherited in an autosomal recessive manner. Treatment is based on the signs and symptoms present in each person. | |

Mental development is usually normal, though a few cases with intellectual impairment have been reported. The signs and symptoms of Hartnup disease incude skin photosensitivity, neurologic findings, psychiatric symptoms, and ocular (eye) findings. Hartnup disease is caused by mutations in the SLC6A19 gene and is inherited in an autosomal recessive manner.[1][2] People with Hartnup disease may benefit from a high-protein diet, protection from sunlight, vitamin supplementation, and avoidance of certain drugs/medications. In some cases, treatment with nicotinamide supplements and tryptophan ethyl ester may be indicated. | |

What is (are) Primary hyperparathyroidism ? | Hyperparathyroidism is an endocrine disorder in which the parathyroid glands in the neck produce too much parathyroid hormone (PTH). Signs and symptoms are often mild and nonspecific, such as a feeling of weakness and fatigue, depression, or aches and pains. With more severe disease, a person may have a loss of appetite, nausea, vomiting, constipation, confusion or impaired thinking and memory, and increased thirst and urination. Patients may have thinning of the bones without symptoms, but with risk of fractures. There are two main types of hyperparathyroidism: primary hyperparathyroidism and secondary hyperparathyroidism. Surgery to remove the parathyroid gland(s) is the main treatment for the disorder. Some patients with mild disease do not require treatment. | |
What is (are) Cogan-Reese syndrome ? | Cogan-Reese syndrome is one type of Iridocorneal Endothelial (ICE) syndrome. The ICE syndromes predominantly affect Caucasian, young to middle-aged women, and involve one eye. While there have been some cases of Cogan-Reese syndrome reported in children, the disease is typically observed in females in the mid-adult years. [1] In one study of 71 patients with ICE syndrome, the mean age at diagnosis was 51-years. Known glaucoma was present in 11 (15%) of cases. [2] While it is not yet known how to keep Cogan-Reese syndrome from progressing, the glaucoma associated with the disease can be treated with medication. Additionally, corneal transplant can treat any corneal swelling. The National Eye Institute provides information on screening for glaucoma HERE. | |
What is (are) Muir-Torre syndrome ? | Muir-Torre syndrome (MTS) is a form of Lynch syndrome and is characterized by sebaceous (oil gland) skin tumors in association with internal cancers. The most common internal site involved is the gastrointestinal tract (with almost half of affected people having colorectal cancer), followed by the genitourinary tract. Skin lesions may develop before or after the diagnosis of the internal cancer. MTS is caused by changes (mutations) in the MLH1 or MSH2 genes and is inherited in an autosomal dominant manner. A mutation in either of these genes gives a person an increased lifetime risk of developing the skin changes and types of cancer associated with the condition. | |
What are the symptoms of Muir-Torre syndrome ? | What are the signs and symptoms of Muir-Torre syndrome? Sebaceous adenoma is the most characteristic finding in people with Muir-Torre syndrome (MTS). Other types of skin tumors in affected people include sebaceous epitheliomas, sebaceous carcinomas (which commonly occur on the eyelids) and keratoacanthomas. Sebaceous carcinoma of the eyelid can invade the orbit of the eye and frequently metastasize, leading to death. Tumors at other sites can also metastasize, but are less likely to cause death. Common sites of keratocathomas include the face and the upper side of the hands, but they can occur anywhere on the body. The most common internal cancer in people with MTS is colorectal cancer, occurring in almost half of affected people. The second most common site is the genitourinary tract. Other cancers that may occur include breast cancer, lymphoma, leukemia (rarely), salivary gland tumors, lower and upper respiratory tract tumors, and chondrosarcoma. Intestinal polyps as well as various benign tumors may also occur. The Human Phenotype Ontology provides the following list of signs and symptoms for Muir-Torre syndrome.

What causes Muir-Torre syndrome ? | What causes Muir-Torre syndrome? Muir-Torre syndrome is a subtype of Lynch syndrome and may be caused by changes (mutations) in either the MLH1, MSH2, or MSH6 gene. These genes give the body instructions to make proteins needed for repairing DNA. The proteins help fix mistakes that are made when DNA is copied before cells divide. When one of these genes is mutated and causes the related protein to be absent or nonfunctional, the number of DNA mistakes that do not get repaired increases substantially. The affected cells do not function normally, increasing the risk of tumor formation. The MSH2 gene is responsible for MTS in the majority of cases. Mutations in MLH1 and MSH2 have the most severe effect. Not everyone diagnosed with MTS will have a detectable mutation in one of these genes. Other, unidentified genes may also play a role in the development of the condition. | |
Is Muir-Torre syndrome inherited ? | How is Muir-Torre syndrome inherited? Muir-Torre-syndrome (MTS) is a variant of Lynch syndrome and is inherited in an autosomal dominant manner. This means that having only one changed (mutated) copy of the responsible gene in each cell is enough for a person to develop the condition. When a person with an autosomal dominant condition has children, each child has 50% (1 in 2) chance to inherit the mutated copy of the responsible gene. It is important to note that people who inherit a mutated gene that causes MTS inherit an increased risk of cancer, not the disease itself. Not all people who inherit a mutation in an associated gene will develop cancer. This phenomenon is called reduced penetrance. The majority of people diagnosed with a form of Lynch syndrome have inherited the mutated gene from a parent. However, because not all people with a mutation develop cancer, and the variable age at which cancer may develop, not all people with a mutation have a parent who had cancer. Thus, the family history may appear negative. A positive family history of MTS is identified in roughly 50% of affected people. The percentage of people with Lynch syndrome who have a new mutation in the gene that occurred for the first time (and was not inherited from a parent) is unknown but is estimated to be extremely low. | |
How to diagnose Muir-Torre syndrome ? | How is Muir-Torre syndrome diagnosed? A person is suspected to have Muir-Torre syndrome (MTS)if he/she has one or more of the following: History of one or more sebaceous tumors Age younger than 60 years at first presentation of sebaceous tumors Personal history of Lynch-related cancers Family history of Lynch-related cancers The presence of specific skin tumors in MTS may lead to the correct diagnosis even in the absence of a clear family history. A person diagnosed with MTS can also have genetic testing to see if they have a mutation in one of the genes known to cause MTS. However, not everyone with Muir-Torre syndrome will have a detectable mutation in one of these genes. Other, unidentified genes may also play a role in the development of the condition. | |
What is (are) Amelogenesis imperfecta ? | Amelogenesis imperfecta (AI) (amelogenesis - enamel formation; imperfecta - imperfect) is a disorder that affects the structure and appearance of the enamel of the teeth. This condition causes teeth to be unusually small, discolored, pitted or grooved, and prone to rapid wear and breakage. These dental problems, which vary among affected individuals, can affect both primary (baby) teeth and permanent teeth. There are 4 main types of AI that are classified based on the type of enamel defect. These 4 types are divided further into 14 subtypes, which are distinguished by their specific dental abnormalities and by their pattern of inheritance. AI can be inherited in an autosomal dominant, autosomal recessive or X-linked recessive pattern. | |
What are the symptoms of Amelogenesis imperfecta ? | What are the signs and symptoms of amelogenesis imperfecta? In general, the both primary and permanent teeth are affected. The enamel tends to be soft and weak, and the teeth appear yellow and damage easily. The defects associated with amelogeneis imperfecta are highly variable and include abnormalities classified as hypoplastic (defects in the amount of enamel), hypomaturation (defect in the final growth and development of the tooth enamel), and hypocalcification (defect in the initial stage of enamel formation followed by defective tooth growth). The enamel in the hypomaturation and hypocalcification types is not mineralized and is thus described as hypomineralized. Traditionally, the diagnosis and classification of amelogenesis imperfecta is based on the clinical presentation and the mode of inheritance. There are four principal types based on the defects in the tooth enamel. These types are subdivided into 14 different subtypes based on the clinical presentation and the mode of inheritance. Detailed information about the signs and symptoms associated with the four major types of amelogenesis imperfecta is available from the UNC School of Dentistry. | |
What causes Amelogenesis imperfecta ? | What causes amelogenesis imperfecta? Amelogenesis imperfecta is caused by mutations in the AMELX, ENAM, and MMP20 genes. These genes provide instructions for making proteins that are essential for normal tooth development. These proteins are involved in the formation of enamel, which is the hard, calcium-rich material that forms the protective outer layer of each tooth. Mutations in any of these genes alter the structure of these proteins or prevent the genes from making any protein at all. As a result, tooth enamel is abnormally thin or soft and may have a yellow or brown color. Teeth with defective enamel are weak and easily damaged. In some cases, the genetic cause of amelogenesis imperfecta can not been identified. Researchers are working to find mutations in other genes that are responsible for this disorder. Click on each gene name to learn more about the role it plays in the development of tooth enamel. | |
Is Amelogenesis imperfecta inherited ? | How is amelogenesis imperfecta inherited? Amelogenesis imperfecta can have different patterns of inheritance, depending on the gene that is altered. Most cases are caused by mutations in the ENAM gene and are inherited in an autosomal dominant pattern. This type of inheritance means one copy of the altered gene in each cell is sufficient to cause the disorder. Amelogenesis imperfecta may also be inherited in an autosomal recessive pattern; this form of the disorder can result from mutations in the ENAM or MMP20 gene. Autosomal recessive inheritance means two copies of the gene in each cell are altered. About 5 percent of amelogenesis imperfecta cases are caused by mutations in the AMELX gene and are inherited in an X-linked pattern. A condition is considered X-linked if the mutated gene that causes the disorder is located on the X chromosome, one of the two sex chromosomes. In most cases, males with X-linked amelogenesis imperfecta experience more severe dental abnormalities than females with this form of this condition. Other cases of amelogenesis imperfecta result from new mutations in these genes and occur in people with no history of the disorder in their family. | |
How to diagnose Amelogenesis imperfecta ? | How is amelogenesis imperfecta diagnosed? A dentist can identify and diagnose amelogenesis imperfecta on the basis of the patient's family history and the signs and symptoms present in the affected individual. Extraoral X-rays (X-rays taken outside the mouth) can reveal the presence of teeth that never erupted o that were absorbed. Intraoral X-rays (X-rays taken inside the mouth) show contrast between the enamel and dentin in cases in which mineralization is affected. Genetic testing is available for the genes AMELX, ENAM, and MMP20. You can visit the Genetic Testing Registry to locate laboratories performing genetic testing for these genes. The American Academy of Pediatric Dentistry is a source of information to find a pediatric dentist. The National Dental Association can also assist people in locating a dentist. | |
What are the treatments for Amelogenesis imperfecta ? | How might amelogenesis imperfecta be treated? Treatment depends on the type of amelogenesis imperfecta and the type of enamel abnormality. Treatments include preventative measures, various types of crowns, as well as tooth implants or dentures in the most severe cases. The social and emotional impact of this condition should also be addressed. Detailed information on the treatment of amelogenesis imperfecta is available from the UNC School of Dentistry. | |

What is (are) Geographic tongue ? | Geographic tongue is a condition that causes chronic and recurrent lesions on the tongue that resemble psoriasis of the skin. It is characterized by pink to red, slightly depressed lesions with irregular, elevated, white or yellow borders. The lesions may also occur in the mucosa of the mouth and labia; this condition is called "areata migrans" because they typically disappear from one area and move to another. The tongue is normally covered with tiny, pinkish-white bumps (papillae), which are actually short, fine, hair-like projections. With geographic tongue, patches on the surface of the tongue are missing papillae and appear as smooth, red "islands," often with slightly raised borders. These patches (lesions) give the tongue a map-like, or geographic, appearance. In most cases there are no symptoms but sometimes it is painful when inflamed. The cause is still unknown. Many researchers think it is linked with psoriasis but more research is needed to better understand the connection. Also, hereditary and environmental factors may be involved. The condition is benign and localized, generally requiring no treatment except reassurance. If painful it may be treated with steroid gels or antihistamine mouth rinses.[12267] | |
What are the symptoms of Geographic tongue ? | What are the signs and symptoms of Geographic tongue? The lesions seen in geographic tongue resemble those of psoriasis. Most patients do not experience symptoms. It has been estimated that about 5% of individuals who have geographic tongue complain of sensitivity to hot or spicy foods when the their lesions are active. The Human Phenotype Ontology provides the following list of signs and symptoms for Geographic tongue. 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. | |
What causes Geographic tongue ? | What causes geographic tongue? Is it genetic? The exact cause of geographic tongue has not been identified. However, because the condition may be present in several members of the same family, genetics may increase a person's chances of developing the condition. A study by Guimares (2007) showed that a specific variant of a gene called IL-1B (interleukin-1 beta) is associated with an increased risk of developing geographic tongue and suggests a genetic basis for the development of the disease. Further research may result in a better understanding of the genetic influences involved in the development of geographic tongue. | |
What are the treatments for Geographic tongue ? | What treatment is available for geographic tongue? Because geographic tongue is a benign (harmless) condition and does not typically cause symptoms, treatment is usually unnecessary. Even those patients who experience sensitivity to hot or spicy foods, generally do not require treatment. With severe symptoms, topical corticosteroids, zinc supplements, and topical anesthetic rinses seem to reduce the discomfort in some patients. | |
What is (are) VACTERL association ? | VACTERL association is a non-random association of birth defects that affects multiple parts of the body. The term VACTERL is an acronym with each letter representing the first letter of one of the more common findings seen in affected individuals: (V) = vertebral abnormalities; (A) = anal atresia; (C) = cardiac (heart) defects; (T) = tracheal anomalies including tracheoesophageal (TE) fistula; (E) = esophageal atresia; (R) = renal (kidney) and radial (thumb side of hand) abnormalities; and (L) = other limb abnormalities. Other features may include (less frequently) growth deficiencies and failure to thrive; facial asymmetry (hemifacial microsomia); external ear malformations; intestinal malrotation; and genital anomalies. Intelligence is usually normal. The exact cause of VACTERL association is unknown; most cases occur randomly, for no apparent reason. In rare cases, VACTERL association has occurred in more than one family member. | |

What causes VACTERL association ? | Is VACTERL association inherited, or does it have a genetic component? A specific, consistent, genetic abnormality has not been identified in individuals with VACTERL association. A very few sporadic cases of VACTERL association have been associated with mutations in FGF8, HOXD13, ZIC3, PTEN, FANCB, FOXF1, and TRAP1 genes and mitochondrial DNA. When a condition is defined as being an "association", it means that it is made up of a series of specific features which have been found to occur together more often than it would happen due to chance alone, but for which no specific cause has been determined (idiopathic). For indiviuals with VACTERL association, the risk for it to recur in either a sibling or a child is usually quoted as being around 1% (1 in 100). There are very few reports of recurrence of the VACTERL association in families in the literature. Researchers have stated that when dysmorphic features, growth abnormalities, and/or learning disability are present in addition to the features of VACTERL association, it may actually be due to a syndrome or chromosome abnormality; if this is the case, the recurrence risk for a family member would be the risk that is associated with that specific diagnosis. Genetic disorders which have features in common with VACTERL association include Feingold syndrome, CHARGE syndrome, Fanconi anemia, Townes-Brocks syndrome, and Pallister-Hall syndrome. It has also been recognized that there is a two to threefold increase in the incidence of multiple congenital malformations (with features that have overlapped with those of VACTERL association) in children of diabetic mothers. | |
How to diagnose VACTERL association ? | Is genetic testing available for VACTERL association? Because there is no known cause of VACTERL association, clinical genetic testing is not available for the condition. If an individual has a specific diagnosis of another syndrome or genetic condition in addition to the features of VACTERL association, genetic testing may be available for that condition. GeneTests lists the names of laboratories that are performing genetic testing for VACTERL association. Although no clinical laboratories are listed for this condition, there are some research laboratories performing genetic testing; to see a list of these laboratories, 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. How is VACTERL association diagnosed? Prenatal diagnosis of VACTERL association can be challenging because certain component features of the condition can be difficult to detect prior to birth. Therefore, the diagnosis of VACTERL association is typically based on features that are seen when a baby is born or in the first few days of life. The diagnosis is based on having at least three of the following features (which make up the acronym VACTERL): vertebral defects, commonly accompanied by rib anomalies; imperforate anus or anal atresia; cardiac (heart) defects; tracheo-esophageal fistula with or without esophageal atresia; renal (kidney) anomalies including renal agenesis, horseshoe kidney, and cystic and/or dysplastic kidneys; and limb abnormalities. Additional types of abnormalities have also been reported in affected individuals and may be used as clues in considering a diagnosis of other conditions with overlapping features. Depending on the features present, some other conditions that may be considered when diagnosing a child who has features of VACTERL association (differential diagnosis) may include Baller-Gerold syndrome, CHARGE syndrome, Currarino disease, 22q11.2 microdeletion syndrome, Fanconi anemia, Feingold syndrome, Fryns syndrome, MURCS association, oculo-auriculo-vertebral spectrum, Opitz G/BBB syndrome, Pallister-Hall syndrome, Townes-Brocks syndrome, and VACTERL with hydrocephalus. | |
What is (are) Harlequin ichthyosis ? | Harlequin ichthyosis is a severe genetic disorder that mainly affects the skin. The newborn infant is covered with plates of thick skin that crack and split apart. The thick plates can pull at and distort facial features and can restrict breathing and eating.

In these cases, the sign or symptom may be rare or common. | |
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. | |
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. | |
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. | |

What is (are) Pustular psoriasis ? | Pustular psoriasis is a rare form of psoriasis that is characterized by widespread pustules and reddish skin. This condition can occur alone or with plaque-type psoriasis. Most cases of pustular psoriasis are thought to be "multifactorial" or associated with the effects of multiple genes in combination with lifestyle and environmental factors. There are several triggers for this conditions including withdrawal from corticosteroids, exposure to various medications and/or infections. Some cases of the generalized form are caused by changes (mutations) in the IL36RN gene and are inherited in an autosomal recessive pattern. In severe cases, hospitalization may be required. Treatment aims to alleviate the associated symptoms and may include certain medications and/or phototherapy. | |

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. | |
What is (are) Holt-Oram syndrome ? | Holt-Oram syndrome is a genetic condition characterized by skeletal abnormalities of the hands and arms (upper limbs) and heart problems. Affected people have at least one bone abnormality in the wrist, many of which can be detected only by X-ray. Additional skeletal abnormalities may also be present. About 75% of affected people have heart problems, including congenital heart defects and/or cardiac conduction disease (an abnormality in the electrical system that coordinates contractions of the heart chambers). Holt-Oram syndrome is caused by mutations in the TBX5 gene and is inherited in an autosomal dominant manner. Most cases result from new mutations in the gene and occur in people with no family history of the condition. | |
What are the symptoms of Holt-Oram syndrome ? | What are the signs and symptoms of Holt-Oram syndrome? People with Holt-Oram syndrome have abnormally developed bones in their upper limbs. At least one abnormality in the bones of the wrist (carpal bones) is present. Additional bone abnormalities may also be present, such as a missing thumb, a long thumb that looks like a finger, partial or complete absence of bones in the forearm, an underdeveloped bone of the upper arm, and abnormalities of the collar bone or shoulder blades. About 75% of affected people have heart problems, which can be life-threatening. The most common problems are an atrial septal defect (ASD) and a ventricular septal defect (VSD). Some people have cardiac conduction disease, which is caused by abnormalities in the electrical system that coordinates contractions of the heart chambers. Cardiac conduction disease can lead to problems such as a slower-than-normal heart rate (bradycardia) or a rapid and uncoordinated contraction of the heart muscle (fibrillation). The features of Holt-Oram syndrome are similar to those of a condition called Duane-radial ray syndrome but these two disorders are caused by mutations in different genes. The Human Phenotype Ontology provides the following list of signs and symptoms for Holt-Oram syndrome. If the information is available, the table below includes how often the symptom is seen in people with this condition.

What causes Holt-Oram syndrome ? | What causes Holt-Oram syndrome? Holt-Oram syndrome is caused by changes (mutations) in the TBX5 gene. This gene gives the body instructions for making a protein involved in the development of the heart and upper limbs before birth. In particular, this gene seems important for dividing the developing heart into four chambers, and in regulating the development of bones in the arms and hands. When the TBX5 gene doesn't function properly, the features of Holt-Oram syndrome result. In some cases the mutation occurs for the first time in an affected person, while in other cases the mutation is inherited from a parent. However, in both of these cases, there is nothing a parent can do to cause this mutation or condition in a child. | |
Is Holt-Oram syndrome inherited ? | How is Holt-Oram syndrome inherited? Holt-Oram syndrome (HOS) is inherited in an autosomal dominant manner. This means that having only one changed (mutated) copy of the responsible gene in each cell is enough to cause signs and symptoms of the condition. In most cases, the mutation in the gene occurs for the first time in the affected person and is not inherited from a parent. When a mutation occurs for the first time, it is called a de novo mutation. This is what typically occurs when there is no family history of the condition. A de novo mutation is due to a random change in the DNA in an egg or sperm cell, or right after conception. In some cases, an affected person inherits the mutated copy of the gene from an affected parent. In these cases, the symptoms and severity can differ from those of the affected parent. When a person with an autosomal dominant condition has children, each child has a 50% (1 in 2) risk to inherit the condition. | |
How to diagnose Holt-Oram syndrome ? | How is Holt-Oram syndrome diagnosed? The diagnosis of Holt-Oram syndrome can be established based on physical features and family history. It can be confirmed through genetic testing looking for mutations in the TBX5 gene. Hand x-rays are usually performed for upper-limb malformations. A family history of this condition and/or cogenital heart malformations is also used as a diagnostic tool as a congenital heart malformation is present in 75% of individuals with Holt-Oram syndrome. An echocardiogram and electrocardiogram can be used to determine the presence and severity of heart defects and/or cardiac conduction disease. Holt-Oram syndrome can be excluded in individuals with congenital malformations involving the following structures or organ systems: ulnar ray only, kidney, vertebra, head and face region, auditory system (hearing loss or ear malformations), lower limb, anus, or eye. | |
What are the treatments for Holt-Oram syndrome ? | How might Holt-Oram syndrome be treated? The treatment of Holt-Oram syndrome is directed toward the specific symptoms that are apparent in each individual. Treatment may require the coordinated efforts of a team of specialists such as pediatricians, surgeons, cardiologists, orthopedists, and/or other health care professionals. Depending upon the severity of any upper limb abnormalities, treatment may consist of corrective or reconstructive surgery, the use of artificial replacements for portions of the forearms and hands (limb prosthetics), and/or physical therapy to help individuals enhance their motor skills. In those with mild cardiac conduction abnormalities, treatment may not be required. In more severe cases, an artificial pacemaker may be used. An artificial pacemaker overrides the heart's impaired electrical conducting system by sending electrical impulses to the heart that keep the heartbeat at a regular rate. Heart abnormalities may also be treated with certain medications, surgery, and/or other techniques. In such cases, the surgical procedures performed will depend upon the location and severity of the abnormalities and their associated symptoms. Affected individuals with heart defects may also be at risk for bacterial infection and inflammation of the lining of the heart's chambers and valves (endocarditis). So antibiotics should be prescribed before any surgical procedure, including dental procedures such as tooth extractions. In addition, because some individuals with certain heart defects may be susceptible to repeated respiratory infections, physicians may closely monitor such individuals to take preventive steps and to institute antibiotic and/or other appropriate therapies should such infections occur. Early intervention is important to ensure that children with Holt-Oram syndrome reach their potential. Special services that may be beneficial to affected children may include physical therapy and/or other medical, social, and/or vocational services. | |

What is (are) Laron syndrome ? | Laron syndrome is a condition that occurs when the body is unable to utilize growth hormone. It is primarily characterized by short stature. Other signs and symptoms vary but may include reduced muscle strength and endurance; hypoglycemia in infancy; delayed puberty; short limbs (arms and legs); and obesity. It is often caused by changes (mutations) in the GHR gene and is inherited in an autosomal recessive manner. Treatment is focused on improving growth and generally includes injections of insulin-like growth factor 1 (IGF-1). | |
What are the symptoms of Laron syndrome ? | What are the signs and symptoms of Laron syndrome? Laron syndrome is a rare condition in which the body is unable to use growth hormone. The primary symptom is short stature. Although affected people are generally close to average size at birth, they experience slow growth from early childhood. If left untreated, adult males with Laron syndrome typically reach a maximum height of about 4.5 feet and adult females may be just over 4 feet tall. Other signs and symptoms associated with the condition vary but may include: Reduced muscle strength and endurance Hypoglycemia in infancy Delayed puberty Small genitals Thin, fragile hair Dental abnormalities Short limbs (arms and legs) Obesity Distinctive facial features (protruding forehead, a sunken bridge of the nose, and blue sclerae) People affected by Laron syndrome appear to have a reduced risk of cancer and type 2 diabetes.

What causes Laron syndrome ? | What causes Laron syndrome? Laron syndrome is caused by changes (mutations) in the GHR gene. This gene encodes growth hormone receptor, which is a protein found on the outer membrane of cells throughout the body. Growth hormone receptor is designed to recognize and bind growth hormone, which triggers cellular growth and division. When growth hormone is bound to the growth hormone receptors on liver cells, specifically, insulin-like growth factor I (another important growth-promoting hormone) is produced. Mutations in GHR impair the function of growth hormone receptors which interferes with their ability to bind growth hormone. This disrupts normal growth and development of cells and prevents the production of insulin-like growth factor I which causes the many signs and symptoms of Laron syndrome. | |
Is Laron syndrome inherited ? | Is Laron syndrome inherited? Most cases of Laron syndrome 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. Reports exist of rare families in which Laron syndrome appears to be inherited in an autosomal dominant manner. In these cases, a person only needs a change (mutation) in one copy of the responsible gene in each cell. In some cases, an affected person inherits the mutation from an affected parent. Other cases may result from new (de novo) mutations in the gene. These cases occur in people with no history of the disorder in their family. An affected person has a 50% chance with each pregnancy of passing along the altered gene to his or her child. | |
How to diagnose Laron syndrome ? | How is Laron syndrome diagnosed? A diagnosis of Laron syndrome is often suspected based on the presence of characteristic signs and symptoms. Additional testing can then be ordered to confirm the diagnosis and rule out other conditions that cause similar features. This generally includes blood tests to measure the levels of certain hormones that are often abnormal in people with Laron syndrome. For example, affected people may have elevated levels of growth hormone and reduced levels of insulin-like growth factor I. Genetic testing for changes (mutations) in the GHR gene can also be used to confirm a diagnosis in some cases. | |
What are the treatments for Laron syndrome ? | How might Laron syndrome be treated? There is currently no cure for Laron syndrome. Treatment is primarily focused on improving growth. The only specific treatment available for this condition is subcutaneous injections of insulin-like growth factor 1 (a growth-promoting hormone), often called IGF-1. IGF-1 stimulates linear growth (height) and also improves brain growth and metabolic abnormalities caused by long-term IGF-1 deficiency. It has also been shown to raise blood glucose levels, reduce cholesterol, and increase muscle growth. IGF-1 and GH levels should be closely monitored in people undergoing this treatment because overdosage of IGF-I causes a variety of health problems. | |
