Description : Myofibrillar myopathy (MFM) is a noncommittal term that refers to a group of morphologically
homogeneous, but genetically heterogeneous chronic neuromuscular disorders. The morphologic
changes in skeletal muscle in MFM result from disintegration of the sarcomeric Z disc
and the myofibrils, followed by abnormal ectopic accumulation of multiple proteins
involved in the structure of the Z disc, including desmin, alpha-B-crystallin (CRYAB;
123590), dystrophin (300377), and myotilin (TTID; 604103). - Genetic Heterogeneity
of Myofibrillar Myopathy Other forms of MFM include alpha-B crystallinopathy (608810),
caused by mutation in the CRYAB gene; myotilinopathy (609200) and spheroid body myopathy
(182920), both caused by mutation in the myotilin gene;;
Inheritance : Autosomal dominant; Autosomal recessive;
Molecular basis : Caused by mutation in the desmin gene (DES, 125660.0001);
