WebMYH7-related scapuloperoneal myopathy is an inherited muscular dystrophy characterized by weakness and wasting of the muscles in the lower legs and the … WebMYH7 encodes the slow/beta-cardiac myosin heavy chain (MyHC), which is the main MyHC isoform in slow, oxidative, type 1 muscle fibers of skeletal muscle. It is also the major MyHC isoform of cardiac ventricles. Numerous missense mutations in the globular head of slow/beta-cardiac MyHC are associated with familial hypertrophic cardiomyopathy.

(from RefSeq NM_000257) The MYH7 gene on chromosome 14 encodes slow/b-cardiac myosin heavy chain (MyHCI), a class II myosin expressed in slow, type 1 muscle fibers as well as in the heart ventricles. MyHCI is the molecular motor of muscle and forms the backbone of the sarcomere thick filaments [ 1 ]. Meer weergeven Twenty-one patients are described. Twelve are women and nine men.
