Gene: TPM2

Alternate names for this Gene: AMCD1|DA1|DA2B|DA2B4|HEL-S-273|NEM4|TMSB

Gene Summary: This gene encodes beta-tropomyosin, a member of the actin filament binding protein family, and mainly expressed in slow, type 1 muscle fibers. Mutations in this gene can alter the expression of other sarcomeric tropomyosin proteins, and cause cap disease, nemaline myopathy and distal arthrogryposis syndromes. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.

Gene is located in Chromosome: 9

Location in Chromosome : 9p13.3

Description of this Gene: tropomyosin 2

Type of Gene: protein-coding
