Duchenne Muscular Dystrophy (DMD; MIM 310200) is one of the most common and severe type of hereditary muscular dystrophies. The disease is caused by mutations in the dystrophin gene. The dystrophin gene is associated with X-linked recessive Duchenne and Becker muscular dystrophy. This disease occurs almost exclusively in males. The clinical symptoms of muscle weakness usually begin at childhood. The main symptoms of this disorder are gradually muscular weakness. The affected patients have inability to standing up and walking. Death is usually due to respiratory infection or cardiomyopathy. In this article, we have reported the discovery of a new nonsense mutation that creates abnormal stop codon in the dystrophin gene. This mutation was detected using Next Generation Sequencing (NGS) technique. The subject was a 17-year-old male with muscular dystrophy that who was suspected of having DMD. He was referred to Hakim medical genetics center of Neyshabur, IRAN.
