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 |
Placental fibroblast culture; 2 affected maternal uncles have fra(X)(q27); 6% of cultured amniotic fluid cells and 26% of placental fibroblasts showed the fra(X); affected male by Southern analysis |
