160150 | OMIM | Myopathy, centronuclear, 1 (CNM1) | A congenital muscle disorder characterized by progressive muscular weakness and wasting involving mainly limb girdle, trunk, and neck muscles. It may also affect distal muscles. Weakness may be present during childhood or adolescence or may not become evident until the third decade of life. Ptosis is a frequent clinical feature. The most prominent histopathologic features include high frequency of centrally located nuclei in muscle fibers not secondary to regeneration, radial arrangement of sarcoplasmic strands around the central nuclei, and predominance and hypotrophy of type 1 fibers. The gene represented in this entry may act as a disease modifier. MTMR14 mutations affecting enzymatic function have been found in sporadic cases of centronuclear myopathy, one of them carrying a disease-associated mutation in DNM2 (PubMed:17008356). This raises the possibility of MTMR14 being a modifier of the phenotype in some cases of centronuclear myopathy (PubMed:17008356). |
