309550.0004; FRAGILE X MENTAL RETARDATION SYNDROME |
| Identified Mutation |
(CGG)n EXPANSION; The usual cause of the fragile X syndrome is an expanded (CGG)n repeat in the 5-prime noncoding region of the FMR1 gene. |
| Remarks |
Clinically unaffected; donor subject has CGG repeat sizes of 29 in allele 1 and 41 in allele 2 in the 5 prime untranslated region (UTR) of the FMR1 gene; CGG repeat size was determined by testing in 9 independent laboratories using two methods each |
