Description 
Frataxin


This gene is composed of 5 exons and codes for a protein that is found in mitochondria. It is believed the protein acts as iron chaperone involved in iron-sulfur biogenesis and heme biosynthesis. It appears that frataxin is a key component in the mitochondrial oxidative phosphorylation.  Mutations in this gene are associated with hypertrophic cardiomyopathy (HCM).
