Repeat CGG sequences are categorized into four classes based on repeat length: normal (<45 repeats); intermediate (45-54 repeats); premutation (55-200 repeats); and full mutation (>200 repeats).
Fragile X is a trinucleotide repeat disease caused predominantly by the expansion of CGG sequences in the 5' region of the fragile X mental retardation 1 (FMR1) gene.
FXS is a trinucleotide repeat disease caused predominantly by the expansion of CGG sequences in the 5' untranslated region of the Fragile X Mental Retardation 1 (FMR1) gene.
