Myostatin-Related Muscle Hypertrophy (Also known as Muscle Hypertrophy Syndrome) Myostatin-Related Muscle Hypertrophy is a genetic disorder where there is a problem in the gene MSTN, which codes for the production of the protein myostatin, a protien that keeps muscles from As it represents a potential target for stimulating muscle growth and/or preventing muscle wasting, myostatin regulation and functions in the control of muscle mass have been extensively studied. Causative mutations lead to a loss of myostatin function which results in significant skeletal muscle growth accompanied by loss of subcutaneous fat tissue. Individual muscles of mutant animals weighed 2 to 3 times more than those of wildtype animals, and the increase in mass appeared to result from a combination of muscle cell hyperplasia and hypertrophy.
