Barth syndrome


What is Barth syndrome?

Barth syndrome is a relatively rare but serious genetic condition that usually affects boys and men. As of 2017, the best estimate is that it occurs in 1 in 300,000 U.S. births. Barth syndrome usually causes abnormalities with the heart, immune system, muscles, and growth. The condition is known to affect the mitochondria, so it is considered a mitochondrial disease. Mitochondria are important parts within a cell and are responsible for producing energy and other functions.
