Genes can affect lean body mass

Posted on

Current research shows that lean mass is highly heritable. By understanding the genetic contributions to lean mass – an indicator of muscle mass- future treatments may be developed to prevent the loss of lean mass with aging.

With age, some people develop a condition called “sarcopenia” where they lose critical amounts of muscle mass, to the point that they develop functional impairments and disabilities. Scientists are now stressing to pinpoint the genes associated with lean mass that may one day lead to therapies that will curtail loss of lean mass and prevent the onset of such disabilities.
