The cause of DMD, a degenerative disorder that affects nearly 1 in 3,500 male babies, has been attributed to a lack of dystrophin protein. Due to the dystrophin gene’s location on the X chromosome, males, who need only one copy of the gene to contract DMD, are twice as likely to be diagnosed with it as females. Despite valiant efforts, no cure for DMD currently exists. Scientists now think that hope may lie within a common friend - the golden retriever.
