X-Linked Dominant Scapuloperoneal Myopathy
X-linked scapuloperoneal myopathy is an inherited muscular dystrophy characterized by weakness and wasting of the muscles in the lower legs and the area of the shoulder blades. In some individuals, facial muscles may also be affected. While the progression varies from case to case, it tends to be relatively slow. Some cases of scapuloperoneal myopathy are caused by mutations in the FHL1 gene. These cases are inherited in an X-linked dominant manner. Treatment is symptomatic and supportive.
