Question: How to diagnose Amelogenesis imperfecta ?

Answer: 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.
Question: What is (are) Hypolipoproteinemia ?

Answer: Hypolipoproteinemia refers to unusually low levels of fats (lipids) in the blood. Low lipid levels may be caused by rare genetic conditions, or be a sign of another disorder such as overactive thyroid, anemia, undernutrition, cancer, chronic infection, or impaired absorption of foods from the digestive tract. Associated genetic disorders includes abetalipoproteinemia, hypobetalipoproteinemia, and chylomicron retention disease. Symptoms of the genetic or familial form of hypolipoproteinemia varies. In hypobetalipoproteinemia the low density lipoprotein (LDL) cholesterol levels are very low, yet people with this syndrome typically have no symptoms nor require treatment. Other forms result in absent or near absent LDL levels and can cause serious symptoms in infancy and early childhood.
Question: What are the symptoms of Human T-cell leukemia virus type 2 ?

Answer: What are the signs and symptoms of human T-cell leukemia virus, type 2? Human T-cell leukemia virus, type 2 (HTLV-2) generally causes no signs or symptoms. Although HTLV-2 has not been definitively linked with any specific health problems, scientists suspect that some affected people may later develop neurological problems such as:[7046] Sensory neuropathies (conditions that affect the nerves that provide feeling) Gait abnormalities Bladder dysfunction Mild cognitive impairment Motor abnormalities (loss of or limited muscle control or movement, or limited mobility) Erectile dysfunction Although evidence is limited, there may also be a link between HTLV-2 and chronic lung infections (i.e. pneumonia and bronchitis), arthritis, asthma, and dermatitis.
Question: What is (are) Relapsing polychondritis ?

Answer: Relapsing polychondritis (RP) is a rare condition characterized by recurrent inflammation of cartilage and other tissues throughout the body. Cartilage is a tough but flexible tissue that covers the ends of bones at a joint, and gives shape and support to other parts of the body. Ear involvement is the most common feature, but a variety of other areas of the body may be affected, including the costal (rib) cartilage, eyes, nose, airways, heart, vascular (veins) system, skin, joints, kidney, and nervous system. The signs and symptoms vary from person to person depending on which parts of the body are affected. The exact underlying cause of RP is unknown; however, scientists suspect that it is an autoimmune condition. The primary goals of treatment for people with RP are to relieve present symptoms and to preserve the structure of the affected cartilage.
Question: What causes Treacher Collins syndrome ?

Answer: What causes Treacher Collins syndrome? Treacher Collins syndrome (TCS) is caused by changes (mutations) in any of several genes: TCOF1 (in over 80% of cases), POLR1C, or POLR1D. In a few cases, the genetic cause of the condition is unknown. These genes appear to play important roles in the early development of bones and other tissues of the face. They are involved in making proteins that help make ribosomal RNA (rRNA). rRNA is a chemical needed to make new proteins that are necessary for normal function and survival of cells. Mutations in these genes can reduce the production of rRNA, which may cause cells involved in the development of facial bones and tissues to die early. This premature cell death may lead to the signs and symptoms of TCS. It is still unclear why the effects of these mutations are generally limited to facial development.
Question: What is (are) Joubert syndrome ?

Answer: Joubert syndrome is disorder of abnormal brain development that may affect many parts of the body. It is characterized by the absence or underdevelopment of the cerebellar vermis (a part of the brain that controls balance and coordination) and a malformed brain stem (connection between the brain and spinal cord). This gives a characteristic appearance of a molar tooth sign on MRI. Signs and symptoms can vary but commonly include weak muscle tone (hypotonia); abnormal breathing patterns; abnormal eye movements; ataxia; distinctive facial features; and intellectual disability. Various other abnormalities may also be present. Joubert syndrome may be caused by mutations in any of many genes and is predominantly inherited in an autosomal recessive manner. Rarely it may be inherited in an X-linked recessive manner. Treatment is supportive and depends on the symptoms in each person.
Question: What is (are) Duane syndrome type 1 ?

Answer: Duane syndrome type 1 is the most common type of Duane syndrome, an eye movement disorder that is present at birth. People with Duane syndrome have restricted ability to move the affected eye(s) outward toward the ear (abduction) and/or inward toward the nose (adduction). The different types are distinguished by the eye movements that are most restricted. Duane syndrome type 1 is characterized by absent to very restricted abduction and normal to mildly restricted adduction. The eye opening (palpebral fissure) narrows and the eyeball retracts into the orbit with adduction. With abduction, the reverse occurs. One or both eyes may be affected. The majority of cases are sporadic (not inherited), while about 10% are familial. 70% of affected people do not have any other abnormalities at birth (isolated Duane syndrome).
Question: What is (are) Pantothenate kinase-associated neurodegeneration ?

Answer: Pantothenate kinase-associated neurodegeneration (PKAN) is a rare, movement disorder characterized by a progressive degeneration of the nervous system (neurodegenerative disorder). PKAN is generally separated into classic and atypical forms. Children with classic PKAN develop symptoms in the first ten years of life. The atypical form of PKAN usually occurs after the age of ten and progresses more slowly. All individuals with PKAN have an abnormal buildup of iron in certain areas of the brain. A particular change, called the eye-of-the-tiger sign, which indicates an accumulation of iron, is typically seen on magnetic resonance imaging (MRI) scans of the brain in people with this disorder. PKAN is inherited in an autosomal recessive manner and is caused by changes (mutations) in the PANK2 gene.
Question: What are the treatments for Troyer syndrome ?

Answer: How might Troyer syndrome be treated? There are currently no treatments known to prevent or slow the progression of Troyer syndrome. Treatment aims to relieve symptoms of the disease and improve quality of life. Treatment for spasticity involves both exercise and medication, especially baclofen (Lioresal), which is used either orally or by intrathecal pump. Tizanidine, dantrolene (with precautions), and Botox have also been useful in reducing muscle spasticity. Daily physical therapy is recommended. Treatment may also include: Occupational therapy, assistive walking devices, and ankle-foot orthotics as needed Oxybutynin to reduce urinary urgency Antidepressants or mood stabilizers to manage emotional or mood disorders Additional information about the management of Troyer syndrome can be viewed on the GeneReviews Web site.
Question: What is (are) Cone dystrophy ?

Answer: Cone dystrophy is a general term for a group of rare eye disorders that affect the cone cells of the retina. Cone cells allow a person to see color and fine detail, and they work best in bright light. The cone dystrophies can cause a variety of symptoms such as decreased visual clarity when looking straight ahead, a reduced ability to see colors, and an increased sensitivity to light. There are two main subtypes of cone dystrophy, called stationary cone dystrophy and progressive cone dystrophy. The age when symptoms begin, the type and severity of symptoms, and the progression of symptoms are all very different between individuals, even between people with the same type of cone dystrophy. Mutations in many genes have been found to cause cone dystrophy, and the condition can be inherited in an autosomal dominant, autosomal recessive, or x-linked manner.
Question: What is (are) Peters plus syndrome ?

Answer: Peters plus syndrome is a genetic condition characterized by abnormalities of the front part of the eye called the anterior chamber, short stature, cleft lip with or without cleft palate, and distinctive facial features.  The most common eye abnormality is Peters anomaly which involves the thinning and clouding of the cornea and attachment of the iris to the cornea causing blurred vision. Other eye abnormalities such as glaucoma and cataracts are common. The severity of symptoms may vary from person to person. The only gene that has been associated with Peters plus syndrome is B3GALTL. The syndrome is inherited in an autosomal recessive fashion. Treatment varies based on the severity of the symptoms; however, regular appointments with an ophthalmologist and avoidance of agents that increase the risk of glaucoma (e.g., corticosteroids) is recommended.
Question: How to diagnose Spinocerebellar ataxia 2 ?

Answer: Is genetic testing available for spinocerebellar ataxia 2? Yes. Molecular genetic testing (analysis of DNA) is needed for a diagnosis of spinocerebellar ataxia 2 (SCA2). This testing detects abnormal CAG trinucleotide repeat expansions in the ATXN2 gene. Affected people (or people who will later develop symptoms of SCA2) have a copy of the ATXN2 gene that has 33 or more CAG repeats. This testing detects nearly 100% of cases of SCA2. The Genetic Testing Registry (GTR) provides information about the labs that offer genetic testing for SCA2. The intended audience for the GTR is health care providers and researchers. Therefore, patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional.
Question: What causes Primary carnitine deficiency ?

Answer: What causes primary carnitine deficiency? Mutations in the SLC22A5 gene cause primary carnitine deficiency. This gene provides instructions for making a protein called OCTN2 that transports carnitine into cells. Cells need carnitine to bring certain types of fats (fatty acids) into mitochondria, which are the energy-producing centers within cells. Fatty acids are a major source of energy for the heart and muscles. During periods of fasting, fatty acids are also an important energy source for the liver and other tissues. Mutations in the SLC22A5 gene result in an absent or dysfunctional OCTN2 protein. As a result, there is a shortage (deficiency) of carnitine within cells. This deficiency, as well as potential build-up of fatty acids within the cells, causes the signs and symptoms of the condition.
Question: What causes Carotid Artery Disease ?

Answer: Carotid artery disease seems to start when damage occurs to the inner layers of the carotid arteries. Major factors that contribute to damage include:
                
Smoking
                
High levels of certain fats and cholesterol in the blood
                
High blood pressure
                
High levels of sugar in the blood due to insulin resistance or diabetes
                
When damage occurs, your body starts a healing process. The healing may cause plaque to build up where the arteries are damaged.
                
The plaque in an artery can crack or rupture. If this happens, blood cell fragments called platelets will stick to the site of the injury and may clump together to form blood clots. 
                
The buildup of plaque or blood clots can severely narrow or block the carotid arteries. This limits the flow of oxygen-rich blood to your brain, which can cause a stroke.
Question: What is (are) infantile neuronal ceroid lipofuscinosis ?

Answer: Infantile neuronal ceroid lipofuscinosis (NCL) is an inherited disorder that primarily affects the nervous system. Beginning in infancy, children with this condition have intellectual and motor disability, rarely developing the ability to speak or walk. Affected children often have muscle twitches (myoclonus), recurrent seizures (epilepsy), or vision impairment. An unusually small head (microcephaly) and progressive loss of nerve cells in the brain are also characteristic features of this disorder. Children with infantile NCL usually do not survive past childhood.  Infantile NCL is one of a group of NCLs (collectively called Batten disease) that affect the nervous system and typically cause progressive problems with vision, movement, and thinking ability. The different types of NCLs are distinguished by the age at which signs and symptoms first appear.
Question: Is 5-alpha reductase deficiency inherited ?

Answer: This condition is inherited in an autosomal recessive pattern, which means both copies of the SRD5A2 gene in each cell have mutations. Most often, the parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but do not show signs and symptoms of the condition.  Although people who are genetically female (with two X chromosomes in each cell) may inherit mutations in both copies of the SRD5A2 gene, their sexual development is not affected. The development of female sex characteristics does not require DHT, so a lack of steroid 5-alpha reductase 2 activity does not cause physical changes in these individuals. Only people who have mutations in both copies of the SRD5A2 gene and are genetically male (with one X and one Y chromosome in each cell) have the characteristic signs of 5-alpha reductase deficiency.

Question: What is (are) Langer mesomelic dysplasia ?

Answer: Langer mesomelic dysplasia is a disorder of bone growth. Affected individuals typically have extreme shortening of the long bones in the arms and legs (mesomelia). As a result of the shortened leg bones, people with Langer mesomelic dysplasia have very short stature. A bone in the forearm called the ulna and a bone in the lower leg called the fibula are often underdeveloped or absent, while other bones in the forearm (the radius) and lower leg (the tibia) are unusually short, thick, and curved. Some people with Langer mesomelic dysplasia also have an abnormality of the wrist and forearm bones called Madelung deformity, which may cause pain and limit wrist movement. Additionally, some affected individuals have mild underdevelopment of the lower jaw bone (mandible).
Question: What are the genetic changes related to hypochondrogenesis ?

Answer: Hypochondrogenesis is one of the most severe conditions in a spectrum of disorders caused by mutations in the COL2A1 gene. This gene provides instructions for making a protein that forms type II collagen. This type of collagen is found mostly in the clear gel that fills the eyeball (the vitreous) and in cartilage. Cartilage is a tough, flexible tissue that makes up much of the skeleton during early development. Most cartilage is later converted to bone, except for the cartilage that continues to cover and protect the ends of bones and is present in the nose and external ears. Type II collagen is essential for the normal development of bones and other connective tissues that form the body's supportive framework. Mutations in the COL2A1 gene interfere with the assembly of type II collagen molecules, which prevents bones and other connective tissues from developing properly.
Question: What are the genetic changes related to alpha thalassemia X-linked intellectual disability syndrome ?

Answer: Alpha thalassemia X-linked intellectual disability syndrome results from mutations in the ATRX gene. This gene provides instructions for making a protein that plays an essential role in normal development. Although the exact function of the ATRX protein is unknown, studies suggest that it helps regulate the activity (expression) of other genes. Among these genes are HBA1 and HBA2, which are necessary for normal hemoglobin production.  Mutations in the ATRX gene change the structure of the ATRX protein, which likely prevents it from effectively regulating gene expression. Reduced activity of the HBA1 and HBA2 genes causes alpha thalassemia. Abnormal expression of other genes, which have not been identified, probably causes developmental delay, distinctive facial features, and the other signs and symptoms of alpha thalassemia X-linked intellectual disability syndrome.

Question: Is spinal and bulbar muscular atrophy inherited ?

Answer: This condition is 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 males (who have only one X chromosome), a mutation in the only copy of the gene in each cell causes the disorder. In most cases, males experience more severe symptoms of the disorder than females (who have two X chromosomes). Females with a mutation in one copy of the AR gene in each cell are typically unaffected. A few females with mutations in both copies of the gene have had mild features related to the condition, including muscle cramps and occasional tremors. Researchers believe that the milder signs and symptoms in females may be related to lower androgen levels.  A characteristic of X-linked inheritance is that fathers cannot pass X-linked traits to their sons.

Question: What are the genetic changes related to alkaptonuria ?

Answer: Mutations in the HGD gene cause alkaptonuria. The HGD gene provides instructions for making an enzyme called homogentisate oxidase. This enzyme helps break down the amino acids phenylalanine and tyrosine, which are important building blocks of proteins. Mutations in the HGD gene impair the enzyme's role in this process. As a result, a substance called homogentisic acid, which is produced as phenylalanine and tyrosine are broken down, accumulates in the body. Excess homogentisic acid and related compounds are deposited in connective tissues, which causes cartilage and skin to darken. Over time, a buildup of this substance in the joints leads to arthritis. Homogentisic acid is also excreted in urine, making the urine turn dark when exposed to air.
Question: What are the genetic changes related to hand-foot-genital syndrome ?

Answer: Mutations in the HOXA13 gene cause hand-foot-genital syndrome. The HOXA13 gene provides instructions for producing a protein that plays an important role in development before birth. Specifically, this protein appears to be critical for the formation and development of the limbs (particularly the hands and feet), urinary tract, and reproductive system. Mutations in the HOXA13 gene cause the characteristic features of hand-foot-genital syndrome by disrupting the early development of these structures. Some mutations in the HOXA13 gene result in the production of a nonfunctional version of the HOXA13 protein. Other mutations alter the protein's structure and interfere with its normal function within cells. Mutations that result in an altered but functional HOXA13 protein may cause more severe signs and symptoms than mutations that lead to a nonfunctional HOXA13 protein.
Question: What is (are) Smoking and the Digestive System ?

Answer: The digestive system is made up of the gastrointestinal (GI) tractalso called the digestive tractand the liver, pancreas, and gallbladder. The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. The hollow organs that make up the GI tract are the mouth, esophagus, stomach, small intestine, large intestinewhich includes the colon and rectumand anus. Food enters the mouth and passes to the anus through the hollow organs of the GI tract. The liver, pancreas, and gallbladder are the solid organs of the digestive system. The digestive system helps the body digest food, which includes breaking food down into nutrients the body needs. Nutrients are substances the body uses for energy, growth, and cell repair.
Question: Who is at risk for Bile Duct Cancer (Cholangiocarcinoma)? ?

Answer: Having colitis or certain liver diseases can increase the risk of bile duct cancer. Anything that increases your risk of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesn't mean that you will not get cancer. People who think they may be at risk should discuss this with their doctor.    Risk factors for bile duct cancer include the following conditions:         - Primary sclerosing cholangitis (a progressive disease in which the bile ducts become blocked by inflammation and scarring).    -  Chronic ulcerative colitis.    -  Cysts in the bile ducts (cysts block the flow of bile and can cause swollen bile ducts, inflammation, and infection).    - Infection with a Chinese liver fluke parasite.
