Riboflavin-responsive exercise intolerance
From WikiMD's WELLNESSPEDIA
Riboflavin-responsive exercise intolerance is a rare genetic disorder that is caused by a deficiency in the enzyme riboflavin-responsive glutathione reductase. This disorder affects the body's ability to produce energy during exercise, leading to muscle weakness and fatigue. Treatment typically includes high doses of riboflavin, which can improve the body's ability to produce energy and reduce symptoms.
