Key result
Mutations in the beta-tropomyosin (TPM2) gene altered tropomyosin isoform composition, leading to reduced levels of gamma-TM and high levels of beta-tropomyosin in patient muscle specimens.

TPM2 mutations may contribute to muscle weakness via isoform imbalance; leaves open mechanistic and therapeutic roles in congenital myopathies.
Observational
Mutations in the beta-tropomyosin gene alter the expression of other sarcomeric TM isoforms, potentially contributing to muscle weakness in neuromuscular disorders.
Nilsson et al. (2008) conducted an observational in Neuromuscular disorders. TPM2 mutations was evaluated on Expression of TM isoforms. Mutations in the beta-tropomyosin (TPM2) gene altered tropomyosin isoform composition, leading to reduced levels of gamma-TM and high levels of beta-tropomyosin in patient muscle specimens.
