Duchenne Muscular Dystrophy

Duchenne muscular dystrophy is a disorder that involves muscle weakness and loss of muscle tissue that gets progressively worse over time. It starts in childhood and becomes progressively worse over time. Duchenne muscular dystrophy is inherited through a genetic defect on an X chromosome. This disorder is most commonly known to effect males more then females, this is because women have two X chromosomes and the dominant X will compensate for the defect on the recessive X chromosome and she will become a carrier of the disorder rather then be affected by it. This means that she will probably pass the defect to her children. Male have both an X chromosome (from their mother) and a Y chromosome (from their father), if the X chromosome that is received from their mothers has the defect it will be attached to that one copy of the X and will then cause the disorder.

Duchenne's muscular dystrophy has no cure but scientists have found; identification of the protein responsible for the disorder and that the isolation of the gene on the X chromosome that codes for the defective protein; the gene affected people will inherit from their mothers. (Muscular Dystrophy Association, New York). The research comes from the University of Manitoba Edward Rosenmann's biochemistry team. They have found the protein that is missing in the cells of patients suffering from this disorder; this missing protein is responsible for Duchenne. The geneticists studying this disorder are all working together to find a way to isolate the gene responsible for duchennce. They estimate to locate the gene in about four or five years, using many methods; one being comparison between people with the disorder and there healthy siblings it order to see the differences between the two and...
