Furthermore, humans with mutations leading to myostatindeficiencies have been identified and found to have increasedmuscle mass. The most cited report was published in the NewEngland Journal of Medicine and describes a newborn withincreased muscle mass compared with other newborns [52].This child was found to have a myostatin null mutation andapart from increased muscle mass had no mental or physicalabnormalities.
