Duchenne Muscular Dystrophy is one of the twenty known types of
             Muscular Dystrophy Diseases. Also called DMD, this disease is one of forty
             neuro-muscular diseases that changes lives daily. This disease is the most
             common childhood disease out of all of the neuro-muscular diseases, affecting
             one in every 3,500 boys in the world. The outcome of DMD is usually inevitable,
             a result of death before the age of 25. However, the receivable information,
             increasing medical advances, and growing support for this crippling disease has
             cushioned the blow to families everywhere.
             Duchenne Muscular Dystrophy starts at conception, when a mutation in
             the gene of the X chromosome occurs. This type of Muscular Dystrophy can
             only affect males, being either passed down from mother to child, or started by a
             new gene mutation. In females, cell nuclei consist of two X-chromosomes.
             When a gene defect occurs on the leg of one X-chromosome, the duplicate leg
             on the other X-chromosome carries back-up genetic information. Because of
             this extra X, girls do not receive the consequences of DMD. In males, there is
             no duplicate back-up leg on the Y-chromosome to compensate for the X-
             chromosome's defect, causing the mutation to slowly disintegrate the muscles of
