| Allelic Variant 2 |
R221W; ATAXIA, FRIEDREICH-LIKE, WITH ISOLATED VITAMIN E DEFICIENCY |
| Identified Mutation |
ARG221TRP |
| Remarks |
Clinically affected with Friedreich-like ataxia; marked weakness; hypotonia; cerebellar deficit; sensory deficit; abolished muscle stretch reflexes; for this donor subject the GAA triplet repeat expansion in the first intron of the frataxin gene is within the normal range for both alleles; donor subject is homozygous for a C>T transition at nucleotide 661 of the TTPA gene resulting in an arg to trp substitution at codon 221 [Arg221Trp (R221W)]; similarly affected brother (not in repository); slow growing culture; |
