DMD is the most common and leading fatal genetic disorder in children, affecting approximately 1 in 5,000 male births with an estimated 300,000 sufferers worldwide today. Currently, there is no cure; DMD is 100% fatal. DMD is found primarily in boys. The dystrophin gene, which regulates dystrophin production, is located on the X-chromosome. Males, who each have one X- and Y-chromosome, are at risk for X-chromosome related disorders. Duchenne may be unknowingly passed from mother to child.
