Abstract excerpt

The prevalence of the fragile X mental retardation (FMR) 1 and FMR2 full mutations (fM) was examined among 1014 school-age children with academic difficulties but without mental retardation. Both Southern blot and polymerase chain reaction analyses for FMR1 and FMR2 were performed on samples obtained from these children. No fM genes were found, and one FMR1 premutation was identified. The distribution of allele...
