QF-PCR as a molecular-based method for autosomal aneuploidies detection
Abstract: Objectives: The currently available methods for rapid prenatal diagnosis of common chromosomal aneuploidies are either Interphase-Fluorescence in Situ Hybridisation (I-FISH) or Quanti- tative Fluorescent Polymerase Chain Reaction (QF-PCR). QF-PCR represents a rapid, high throughput, cost-effective alternative for Interphase-FISH. The objective of the study was to evaluate the performance of QF-PCR, as a molecular-based technique for the detection of chromosome 21, 18 and 13 copy numbers. Study design: A retrospective cohort of 163 samples referred for screening of common chromosomal aneuploidies was blindly tested for chromosome 21, 18 and 13 copy numbers using QF-PCR and the results were compared with those of conventional cytogenetic analysis. Results: QF-PCR demonstrated optimal sensitivity and specificity (100%) for non mosaic trisomies. QF-PCR was able to consistently detect maternal cell contamination and mosaic trisomies when the trisomic cell line was present at an adequate level (23% or more). However, QF-PCR was unable to detect chromosomal rearrangements for which the primers were not designed. Conclusion: QF- PCR proved its superior performance as a molecular-based method for autosomal aneuploidy detection concerning both sensitivity and specificity.
