Technical validation of a TM Biosciences Luminex-based multiplex assay for detecting the American College of Medical Genetics recommended cystic fibrosis mutation panel.

The American College of Medical Genetics (ACMG) and the American College of Obstetrics and Gynecology have recommended population-based carrier screening for cystic fibrosis to include 23 mutations and 5 polymorphisms in the cystic fibrosis transmembrane regulator gene(CFTR). We estimate 20% of all pregnant women are being tested for their CF carrier status. We assessed two commercially available analyte-specific reagents (ASRs) capable of testing all 25 mutations of the original ACMG-recommended panel, Tag-It CFTR40 + 4 Luminex-based reagent from Tm Biosciences, and our current assay platform, CF Genotyper V.
