Tests & Diagnosis
Myostatin-related muscle hypertrophy is diagnosed based upon the clinical signs and symptoms in the patient (i.e, reduced body fat and increased muscle size) and genetic testing. Body fat can be measured by ultrasound or with a caliper. Skeletal muscle size can be measured by ultrasound, dual-energy x-ray absorptiometry (DEXA), or MRI. Myostatin-related muscle hypertrophy is a very rare condition that is caused by mutations in the MSTN gene. Clinical genetic testing for this condition appears to be available on a limited basis.
