Abstract excerpt

Considerable research has focused on patients with trinucleotide (CGG) repeat expansions in the fragile X mental retardation 1 (FMR1) gene that fall within either the full mutation (>200 repeats) or premutation range (55-200 repeats). Recent interest in individuals with gray zone expansions (41-54 CGG repeats) has grown due to reported phenotypes that are similar to those observed in premutation carriers,...
