Abstract excerpt
Facioscapulohumeral muscular dystrophy 1 (FSHD1) is caused by a contraction in the number of D4Z4 repeats on chromosome 4, resulting in relaxation of D4Z4 chromatin causing inappropriate expression of DUX4 in skeletal muscle. Clinical severity is inversely related to the number of repeats. In contrast, FSHD2 patients also have inappropriate expression of DUX4 in skeletal muscle, but due to constitutional...
