Emery-Dreifuss Muscular Dystrophy 1, X-Linked, also known as muscular dystrophy, tardive, dreifuss-emery type, with contractures, is related to myopathy, x-linked, with postural muscle atrophy and first-degree atrioventricular block, and has symptoms including waddling gait An important gene associated with Emery-Dreifuss Muscular Dystrophy 1, X-Linked is EMD (Emerin), and among its related pathways/superpathways are Cell Cycle, Mitotic and Separation of Sister Chromatids. Affiliated tissues include skeletal muscle and heart, and related phenotypes are skeletal muscle atrophy and elevated circulating creatine kinase concentration
