Myostatin-related muscle hypertrophy is a rare genetic condition that causes people to grow significantly more muscle mass than is considered normal. It is also associated with lower amounts of body fat. People with the condition can have normal strength or be stronger than average. The prevalence of myostatin-related muscle hypertrophy is unknown, but spontaneous mutations within the MSTN gene are extremely rare.

Myostatin-related muscle hypertrophy is a rare genetic condition that causes a person to grow significantly more muscle mass than what is considered normal
Myostatin-related muscle hypertrophy is caused by a deficiency in the MSTN gene, which helps the body make the protein myostatin. This protein is active in skeletal muscles and normally controls and limits muscle growth. The condition is typically recognised at birth or during infancy, when infants and children with the condition often measure above average on weight charts.
The main symptom of myostatin-related muscle hypertrophy is the presence of enlarged muscles, particularly in the thighs, calves, and upper arms. People with the condition can have normal strength or be stronger than average. The condition is not known to cause any medical problems, and affected individuals are intellectually normal. No treatment is needed for myostatin-related hypertrophy, as it is not painful and does not cause any other health conditions or medical issues.
The prevalence of myostatin-related muscle hypertrophy is unknown, but the incidence of spontaneous mutations within the MSTN gene is extremely rare.

The condition is not painful and does not cause any other health conditions or medical issues
Myostatin-related muscle hypertrophy is a rare genetic condition that causes a person to grow significantly more muscle mass than what is considered normal. It is not painful and does not cause any other health conditions or medical issues.
The condition is characterised by reduced body fat and increased muscle size. Individuals with myostatin-related muscle hypertrophy can have up to twice the usual amount of muscle mass in their bodies. They also tend to have increased muscle strength, which can be normal or above average. The main symptom of the condition is the presence of enlarged muscles, particularly in the thighs, calves, and upper arms.
Myostatin-related muscle hypertrophy is caused by variants or mutations in the MSTN gene, which provides instructions for making a protein called myostatin. This protein is active in skeletal muscles, both before and after birth, and normally controls and limits muscle growth. The condition is typically recognised at birth or during infancy, when infants and children with the condition often measure above average on weight charts.
The prevalence of myostatin-related muscle hypertrophy is unknown, but it is considered extremely rare. No treatment is needed for the condition, and affected individuals are intellectually normal.

Myostatin-related muscle hypertrophy is typically recognised at birth or during infancy
Myostatin-related muscle hypertrophy is a rare genetic condition that causes a person to grow significantly more muscle mass than what is considered normal. The condition is typically recognised at birth or during infancy, and infants and children with the condition often measure above average on weight charts. Myostatin-related muscle hypertrophy is characterised by reduced body fat and increased muscle size. Affected individuals have up to twice the usual amount of muscle mass in their bodies, as well as increased muscle strength. The condition is diagnosed with a physical examination, imaging to measure muscle mass and body fat, and genetic testing to confirm a mutation in the MSTN gene.
The MSTN gene provides instructions for making a protein called myostatin, which is active in muscles used for movement (skeletal muscles) both before and after birth. Myostatin normally controls and limits muscle growth. Myostatin-related muscle hypertrophy results from a deficiency of the MSTN gene, which causes the absence of myostatin. The main symptom of the condition is the presence of enlarged muscles, particularly in the thighs, calves, and upper arms.
Myostatin-related muscle hypertrophy is not known to cause any medical problems, and affected individuals are intellectually normal. No treatment is needed for the condition, which is not painful and does not cause any other health conditions or medical issues. The prevalence of myostatin-related muscle hypertrophy is unknown.

The prevalence of myostatin-related muscle hypertrophy is unknown. However, the extremely rare incidence of spontaneous mutations within the MSTN gene suggests that the condition may confer a biological advantage and be subject to evolutionary constraints on muscle size.
