A nemaline myopathy mutation in alpha-tropomyosin causes defective regulation of striated muscle force production.

Abstract excerpt

Nemaline myopathy (NM) is a rare autosomal dominant skeletal muscle myopathy characterized by severe muscle weakness and the subsequent appearance of nemaline rods within the muscle fibers. Recently, a missense mutation inTPM3, which encodes the slow skeletal alpha-tropomyosin (alphaTm), was linked to NM in a large kindred with an autosomal-dominant, childhood-onset form of the disease. We used adenoviral gene...
