Abstract

Background: High-throughput genotyping allows rapid identification of targeted mutations at a fraction of the cost of current gene-by-gene testing methodologies. An objective comparison of the two methodologies allows providers to assess the clinical validity/utility of high-throughput carrier screening and establish a comfort level with new genomic technologies. Aim: To verify that high-throughput genotyping accurately determines patient carrier status, DNA samples from previously identified carriers (n=31) of Ashkenazi Jewish genetic diseases were anonymized and submitted for retesting by high-throughput genotyping. Results: The results were 100% concordant (95% CI: 0.998-1), demonstrating that high-throughput genotyping assays accurately identify carriers of targeted mutations in the Ashkenazi Jewish population. In addition, carrier status for diseases and mutations not previously tested was uncovered using the high-throughput assay. Conclusions: High-throughput genotyping is a cost-effective and clinically valid approach to carrier screening. The use of a broader screen for Ashkenazi Jewish individuals increases the detection of carriers in this population.
