摘要：
Fragile X mental retardation is associated with an unstable expansion of a CGG repeat in the FMR-1 gene on the X chromosome (Xq27.3). We asked whether variation in the number of FMR-1 CGG repeats relates to IQ in the general population. FMR-1 CGG repeats were genotyped for three groups: low IQ (mean IQ = 71, N = 35), middle IQ (mean IQ = 103, N = 19), and high IQ (mean IQ = 137, N = 49). The IQ groups did not differ significantly in number of FMR-1 CGG repeats for males or females.
