MSTN

Musculoskeletal System · Myogenesis & Satellite Cell Renewal

Does an MSTN variant guarantee unusually large muscles?

MSTN makes myostatin, a signal that normally limits skeletal-muscle growth. Certain changes can alter that restraint, but the effect depends on the exact variant rather than the presence of the gene on a report.

Common Gene Name
myostatin
NCBI Gene ID
2660
Chromosome
2
