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. |
