Overview
It is understood that Friedreich’s ataxia is the result of a homozygous guanine–adenine–adenine (GAA) trinucleotide repeat expansion on chromosome 9q13 that causes a transcriptional defect of the frataxin gene. Frataxin is a small mitochondrial protein and deficiency of frataxin is responsible for all clinical and morphological manifestations of Friedreich’s ataxia.
