Allelic Variant 1 |
606829.0001; FRIEDREICH ATAXIA |
Identified Mutation |
(GAA)n EXPANSION; GAA triplet repeat expansions between 200 and 900 copies in the first intron of the frataxin gene occurred in 71 out of 74 FRDA patients studied by Campuzano et al. [Science 271: 1423-1427 (1996)]. In unaffected individuals the triplet expansion numbered between 7 and 20 units. |

Remarks |
Clinically affected; spinal-cerebral degeneration with myocardiopathy; homozygous for the GAA expansion in the frataxin gene with alleles of approximately 330 and 380 repeats; a brother (GM04078/GM04079) is similarly affected. |
