| 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 |
Low-normal IQ; hyperactive; short attention span; 46,fra(X)(q27),Y in PBL; CGG repeats in the FMR1 gene range from 931-940 (normal size range is 5-45 repeats); full mutation (fully methylated) characteristic of Fragile X syndrome; son of GM09238. |
