WebIn FXS, the FMR1 gene is fully methylated. In FXTAS, the FMR1 gene is in its normally unmethylated state. FXS is diagnosed by molecular (DNA) testing of the FMR1 gene. Virtually all boys with a full mutation have FXS and about 50% of girls with a full mutation have features of FXS. FXTAS is diagnosed by fulfilling certain criteria. WebDNA-based molecular analysis (eg, Southern blot analysis and polymerase chain reaction) is the preferred method of diagnosis of fragile X syndrome and of determining FMR1 triplet repeat number (eg, premutations).
