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 unaffected carrier; mild cerebral palsy and hemiparesis; brother of GM15850 and GM15851; donor subject has one allele with GAA triplet repeat expansion of 920 in the first intron of the frataxin gene and the 2nd allele has a # of GAA repeats within normal limits. |
