Summaries for MYOT Gene

Entrez Gene Summary for MYOT Gene

  • This gene encodes a cystoskeletal protein which plays a significant role in the stability of thin filaments during muscle contraction. This protein binds F-actin, crosslinks actin filaments, and prevents latrunculin A-induced filament disassembly. Mutations in this gene have been associated with limb-girdle muscular dystrophy and myofibrillar myopathies. Several alternatively spliced transcript variants of this gene have been described, but the full-length nature of some of these variants has not been determined.[provided by RefSeq, Oct 2008]

  • Limb-girdle muscular dystrophy 1A (LGMD1A) [MIM:159000]: An autosomal dominant degenerative myopathy with onset within a mean age of 28 years. Characterized by progressive skeletal muscle weakness of the hip and shoulder girdles, later progressing to include distal weakness, as well as a distinctive dysarthric pattern of speech. Affected muscle exhibits disorganization and streaming of the Z-line. {ECO:0000269 PubMed:10958653, ECO:0000269 PubMed:12428213}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Myopathy, myofibrillar, 3 (MFM3) [MIM:609200]: A neuromuscular disorder characterized by progressive skeletal muscle weakness greater distally than proximally, tight heel cords, hyporeflexia, cardiomyopathy and peripheral neuropathy in some patients. Affected muscle exhibits disorganization and streaming of the Z-line, presence of large hyaline structures, excessive accumulation of myotilin and other ectopically expressed proteins and prominent congophilic deposits. {ECO:0000269 PubMed:15111675}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Spheroid body myopathy (SBM) [MIM:182920]: Autosomal dominant form of myofibrillar myopathy (MFM), characterized by slowly progressing proximal muscle weakness and dysarthric nasal speech. There is no evidence of cardiomyopathy. Muscle biopsy shows spheroid bodies within the type I muscle fibers. {ECO:0000269 PubMed:16380616}. Note=The disease is caused by mutations affecting the gene represented in this entry.
