New Gene Linked To Muscular Dystrophy

Muscular dystrophy, a group of inherited diseases characterized by progressive skeletal muscle weakness, can be caused by mutations in any one of a number of genes. Another gene can now be added to this list, as Yukiko Hayashi and colleagues, at the National Center of Neurology and Psychiatry, Japan, have now identified mutations in a gene not previously linked to muscular dystrophy as causative of a form of the disease in five nonconsanguineous Japanese patients.
