Effective May 14, 2024, the MLabs MMGL Molecular Genetics Laboratory has modified their Fragile X testing methodology. The primary testing methodology for detection of FMR1 CGG repeats is unchanged. Secondary testing, if needed for the determination of the methylation status of FMR1 will be performed using Asuragen AmplideX mPCR FMR1 test kit; MMGL's laboratory developed test (bisulfite conversion followed by PCR) for FMR1 methylation detection is being retired.
