Muscular hypertrophy (double muscling)

The chain reaches the human disease myostatin-related muscle hypertrophy, which Mondo defines as: “Myostatin-related muscle hypertrophy is a rare condition characterized by reduced body fat and increased muscle size. Affected individuals have up to twice the usual amount of muscle mass in their bodies. They also tend to have increased muscle strength. This condition is not known to cause any medical problems, and affected individuals are intellectually normal. Myostatin-related muscle hypertrophy is caused by mutations in the MSTN gene. It follows an incomplete autosomal dominant pattern of inheritance.”

Human diseases

Two routes lead from an OMIA group to a Mondo human disease: OMIA's own Mondo link, and the group's OMIM numbers through Mondo's cross-references.

Mondo disease Name Found by
MONDO:0013598 myostatin-related muscle hypertrophy Myostatin-related muscle hypertrophy is a rare condition characterized by reduced body fat and increased muscle size. Affected individuals have up to twice the usual amount of muscle mass in their bodies. They also tend to have increased muscle strength. This condition is not known to cause any medical problems, and affected individuals are intellectually normal. Myostatin-related muscle hypertrophy is caused by mutations in the MSTN gene. It follows an incomplete autosomal dominant pattern of inheritance. Both routes
