| Allelic Variant 1 |
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 normal; affected brother and 2 nephews; negative for fra(X) in peripheral blood lymphocytes; normal transmitting male by Southern and PCR analyses; CGG repeat is 100-117; DNA obtained from the donor subject's lymphoblastoid cell line was sequenced in triplicate and the average CGG repeat in the FMR1 gene is 118 |
