Clinical and genetic abnormalities in patients with Friedreich's ataxia.
A Dürr, M Cossee, Y Agid, V Campuzano, C Mignard, C Penet, J L Mandel, A Brice, M Koenig,

Friedreich's ataxia, the most common inherited ataxia, is associated with a mutation that consists of an unstable expansion of GAA repeats in the first intron of the frataxin gene on chromosome 9, which encodes a protein of unknown function.
