Question: What are the genetic changes related to type 1 diabetes ?

Answer: The causes of type 1 diabetes are unknown, although several risk factors have been identified. The risk of developing type 1 diabetes is increased by certain variants of the HLA-DQA1, HLA-DQB1, and HLA-DRB1 genes. These genes provide instructions for making proteins that play a critical role in the immune system. The HLA-DQA1, HLA-DQB1, and HLA-DRB1 genes belong to a family of genes called the human leukocyte antigen (HLA) complex. The HLA complex helps the immune system distinguish the body's own proteins from proteins made by foreign invaders such as viruses and bacteria.  Type 1 diabetes is generally considered to be an autoimmune disorder. Autoimmune disorders occur when the immune system attacks the body's own tissues and organs. For unknown reasons, in people with type 1 diabetes the immune system damages the insulin-producing beta cells in the pancreas. Damage to these cells impairs insulin production and leads to the signs and symptoms of type 1 diabetes.  HLA genes, including HLA-DQA1, HLA-DQB1, and HLA-DRB1, have many variations, and individuals have a certain combination of these variations, called a haplotype. Certain HLA haplotypes are associated with a higher risk of developing type 1 diabetes, with particular combinations of HLA-DQA1, HLA-DQB1, and HLA-DRB1 gene variations resulting in the highest risk. These haplotypes seem to increase the risk of an inappropriate immune response to beta cells. However, these variants are also found in the general population, and only about 5 percent of individuals with the gene variants develop type 1 diabetes. HLA variations account for approximately 40 percent of the genetic risk for the condition. Other HLA variations appear to be protective against the disease. Additional contributors, such as environmental factors and variations in other genes, are also thought to influence the development of this complex disorder.
Question: Is coloboma inherited ?

Answer: Most often, isolated coloboma is not inherited, and there is only one affected individual in a family. However, the affected individual is still at risk of passing the coloboma on to his or her own children.  In cases when it is passed down in families, coloboma can have different inheritance patterns. Isolated coloboma is sometimes inherited in an autosomal dominant pattern, which means one copy of an altered gene in each cell is sufficient to cause the disorder. Isolated coloboma can also be inherited in an autosomal recessive pattern, which means both copies of a gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of a mutated gene, but they typically do not show signs and symptoms of the condition.  Less commonly, isolated coloboma may have X-linked dominant or X-linked recessive patterns of inheritance. X-linked means that a gene associated with this condition is located on the X chromosome, which is one of the two sex chromosomes. A characteristic of X-linked inheritance is that fathers cannot pass X-linked traits to their sons.  X-linked dominant means that in females (who have two X chromosomes), a mutation in one of the two copies of a gene in each cell is sufficient to cause the disorder. In males (who have only one X chromosome), a mutation in the only copy of a gene in each cell causes the disorder. In most cases, males experience more severe symptoms of the disorder than females.  X-linked recessive means that in females, a mutation would have to occur in both copies of a gene to cause the disorder. In males, one altered copy of a gene in each cell is sufficient to cause the condition. Because it is unlikely that females will have two altered copies of a particular gene, males are affected by X-linked recessive disorders much more frequently than females.  When coloboma occurs as a feature of a genetic syndrome or chromosomal abnormality, it may cluster in families according to the inheritance pattern for that condition, which may be autosomal dominant, autosomal recessive, or X-linked.
Question: What are the genetic changes related to Brooke-Spiegler syndrome ?

Answer: Brooke-Spiegler syndrome is caused by mutations in the CYLD gene. This gene provides instructions for making a protein that helps regulate nuclear factor-kappa-B. Nuclear factor-kappa-B is a group of related proteins that help protect cells from self-destruction (apoptosis) in response to certain signals. In regulating the action of nuclear factor-kappa-B, the CYLD protein allows cells to respond properly to signals to self-destruct when appropriate, such as when the cells become abnormal. By this mechanism, the CYLD protein acts as a tumor suppressor, which means that it helps prevent cells from growing and dividing too fast or in an uncontrolled way.  People with Brooke-Spiegler syndrome are born with a mutation in one of the two copies of the CYLD gene in each cell. This mutation prevents the cell from making functional CYLD protein from the altered copy of the gene. However, enough protein is usually produced from the other, normal copy of the gene to regulate cell growth effectively. For tumors to develop, a second mutation or deletion of genetic material involving the other copy of the CYLD gene must occur in certain cells during a person's lifetime.  When both copies of the CYLD gene are mutated in a particular cell, that cell cannot produce any functional CYLD protein. The loss of this protein allows the cell to grow and divide in an uncontrolled way to form a tumor. In people with Brooke-Spiegler syndrome, a second CYLD mutation typically occurs in multiple cells over an affected person's lifetime. The loss of CYLD protein in different types of cells in the skin leads to the growth of a variety of skin appendage tumors.  Some researchers consider Brooke-Spiegler syndrome and two related conditions called multiple familial trichoepithelioma and familial cylindromatosis, which are also caused by CYLD gene mutations, to be different forms of the same disorder. It is unclear why mutations in the CYLD gene cause different patterns of skin appendage tumors in each of these conditions, or why the tumors are generally confined to the skin in these disorders.
Question: What are the symptoms of IgA Nephropathy ?

Answer: In its early stages, IgA nephropathy may have no symptoms; it can be silent for years or even decades. Once symptoms appear, the most common one is hematuria, or blood in the urine. Hematuria can be a sign of damaged glomeruli. Blood in the urine may appear during or soon after a cold, sore throat, or other respiratory infection. The amount of blood may be
                
- visible with the naked eye. The urine may turn pink or the color of tea or cola. Sometimes a person may have dark or bloody urine.  - so small that it can only be detected using special medical tests.
                
Another symptom of IgA nephropathy is albuminuriawhen a persons urine contains an increased amount of albumin, a protein typically found in the blood, or large amounts of protein in the urine. Albumin is the main protein in the blood. Healthy kidneys keep most proteins in the blood from leaking into the urine. However, when the glomeruli are damaged, large amounts of protein leak out of the blood into the urine.
                
When albumin leaks into the urine, the blood loses its capacity to absorb extra fluid from the body. Too much fluid in the body may cause edema, or swelling, usually in the legs, feet, or ankles and less often in the hands or face. Foamy urine is another sign of albuminuria. Some people with IgA nephropathy have both hematuria and albuminuria.
                
After 10 to 20 years with IgA nephropathy, about 20 to 40 percent of adults develop end-stage kidney disease.5 Signs and symptoms of end-stage kidney disease may include
                
- high blood pressure  - little or no urination  - edema  - feeling tired  - drowsiness  - generalized itching or numbness  - dry skin  - headaches  - weight loss  - appetite loss  - nausea  - vomiting  - sleep problems  - trouble concentrating  - darkened skin  - muscle cramps

Question: How to diagnose Neurofibromatosis type 1 ?

Answer: Is genetic testing available for neurofibromatosis type 1? Although it is usually not necessary for diagnosis, genetic testing is available for NF1, the gene known to cause neurofibromatosis type 1. Carrier testing for at-risk relatives and prenatal testing are possible if the disease-causing mutation in the family is known. The Genetic Testing Registry (GTR) is a centralized online resource for information about genetic tests. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional. How is neurofibromatosis type 1 diagnosed? The diagnosis of neurofibromatosis type 1 (NF1) is usually based on the presence of characteristic signs and symptoms. Specifically, doctors look for two or more of the following features to make a diagnosis of NF1: Six or more cafe-au-lait spots (measuring more than 5 mm across in children and more than 15 mm across in adolescents and adults) Two or more neurofibromas of any type or one plexiform neurofibroma (a neurofibroma that involves many nerves) Freckling in the underarm and/or groin Optic glioma Two or more Lisch nodules (clumps of pigment in the colored part of the eye that do not interfere with vision) Bone abnormalities including sphenoid dysplasia (absence of bone surrounding the eye) or tibial pseudarthrosis (incomplete healing of a fracture) A parent, sibling, or child who has been diagnosed with NF1 Because many of the features associated with NF1 develop with age, it can sometimes take several years to make a diagnosis in children without a family history of the condition. Genetic testing for changes (mutations) in the NF1 gene is available, but it is often not necessary. Prenatal testing and preimplantation genetic diagnosis is only an option if the disease-causing mutation in the family is known.
