Extractions: There are many families in the Alport study, so we have tried to develop efficient methods for collagen gene mutation screening. The following table summarizes year by year accumulation of independently ascertained kindreds who actively participate in the University of Utah study, by providing medical information and blood or other specimens. Mutation detection Although we have used various other methods in the past, the most rapid means that we currently have available for molecular diagnosis is mutation detection. By this approach, we attempt to find the specific molecular genetic defect that causes the disease in a particular family. This approach would not be possible unless we knew the specific genes that cause most forms of Alport Syndrome. Since there are 100,000 genes in the human genome and there are thousands of "parts" to each gene that might be defective, it is not now possible to perform a test of ALL of the genes in any single individual. In fact, it is still rather difficult to test even ONE gene in a single individual. Genes vary in size and small genes are easier to "scan" for mutations than big ones. The X-linked Alport gene, COL4A5, happens to be a very large gene. Because COL4A5 is so large, most methods that are used to identify mutations involve breaking the gene down into smaller sub-segments and examining each of these sub-segments for some change that would destroy the normal function of the gene. Since different families almost always have different mutations, the entire gene must be examined in every new family.

Extractions: Genetics and Deafness - Alport Syndrome Alport Syndrome (AS) is characterized by hereditary nephritis (kidney disease known as Bright's disease in the past) and sensorineural hearing loss. The mode of inheritance may be X-linked or autosomal dominant. Less common symptoms include a defect of the lens of the eye called anterior lenticonus and a defect of blood platelets that can cause bleeding complications. AS is usually diagnosed by a test for blood and protein in the urine, hearing tests, and an extended family history. Hearing loss commonly occurs in childhood. - Most subtypes of AS include a bilateral progressive sensorineural hearing loss of mild to moderate degree, but some individuals may have a severe to profound loss. Females generally have a milder hearing loss than their male relatives if they have one at all. Management of the hearing loss includes regular audiologic follow-up, use of hearing aides, and avoidance of certain drugs and excessive noise exposure that can cause further hearing loss.

http://www.boystownhospital.org/parents/info/genetics/current.asp

Extractions: Involved in Hearing Impairment Heredity is the most important factor in the cause of significant hearing impairment in humans. It has been estimated that well over half of all cases of childhood deafness have a genetic cause. A better understanding of the nature of the genes which cause these hearing problems promises to improve our diagnostic abilities and will lay the foundation for research into more effective methods of treatment and remediation. The problems surrounding the study of hereditary deafness are rather daunting. The number of genes involved is large (McKusick's catalogue lists several hundred syndromes that have hearing impairment as one component) and many cases are due to different genes. But we don't yet have the clinical tools to separate cases into fully useful categories.

Extractions: Alport Syndrome Alport Syndrome (AS) is an inherited disorder of the basement membranes of the kidney, eye and ear. People who inherit defective genes for the "collagen" proteins in these basement membranes may develop progressive loss of renal function, deafness and abnormalities of the eye. In the kidneys, glomerular basement membranes normally act like filters, allowing fluid to move from blood vessels to urine while retaining protein and red blood cells within the bloodstream. Thus, one of the early signs of Alport syndrome may be leakage of small amounts of blood or protein into the urine during childhood. Collagen-containing membranes are also important for the shape of the lens of the eye and the structure of the inner ear. History In 1927, Dr. Alport wrote his classic report on a British family with the syndrome. He drew attention to the fact that affected males in this family uniformly developed progressive renal failure and deafness, whereas females were less affected. This pattern of inheritance is termed "X-linked". The normal copy of the gene onto the other X chromosome relatively protects female "carriers" who inherit an abnormal Alport gene on one X chromosome. Some females may develop renal insufficiency, but in general this occurs late in life. In contrast, every male receives one Y chromosome from his father and one X chromosome from his mother; thus, if he happens to inherit an X-chromosome bearing a mutant Alport gene, the boy is unprotected and develops the full-blown Alport Syndrome as a young adult.

Extractions: Alport Syndrome is a group of hereditary kidney disorders characterized by progressive deterioration of the glomerular basement membranes (GBMs), which are microscopic parts of the kidney. This deterioration may lead to chronic renal (kidney) failure causing excess waste products in the blood (uremia). Eventually severe renal failure (end-stage renal disease or ESRD) may develop.
