Conclusion
FragilEase™ PCR, as well as other commercially available kits, efficiently detect FMR1 mutations and simplify the workflow in laboratories that performing FXS diagnoses.
Methods
This study had a retrospective design. We analyzed the performance of the FragilEase™ PCR kit using 90 DNA samples from patients with clinical suspicion of FXS or a family history of the syndrome using capillary electrophoresis and compared with the
Results
FragilEase™ PCR kit displayed high concordance with the results obtained using PCR, SB, and AmplideX FMR1 PCR regarding the detection of normal, intermediate/gray zone, premutation, and full mutation alleles, as well as female homozygosity and mosaicism. The replicate sizes found using the FragilEase™ PCR assay varied on average by two CGG repeats.
