Muscular Dystrophy, Congenital, Megaconial Type; Mdcmc

Description

This form of autosomal recessive congenital muscular dystrophy is characterized by early-onset muscle wasting and mental retardation. Some patients develop fatal cardiomyopathy. Muscle biopsy shows peculiar enlarged mitochondria that are prevalent toward the periphery of the fibers but are sparse in the center (summary by Mitsuhashi et al., 2011).
