Molecular assay reagents intended to identify CGG repeats in the fragile X mental retardation 2 (AFF2) (formerly FMR2) gene, located at chromosome Xq28. The absence of CGG repeats causes an expansion of GCC repeats, which are associated with mental retardation, including X-linked mental retardation fragile site (FRAXE).
