Unveiling Genotypes

In conjunction with the CPT, the laboratory has developed and validated an extensive genotyping panel capable of analyzing numerous DNA variants associated with pharmacogenomics. Key genes, including CYP2D6, TPMT, CYP2C19, and NAT2, are subject to thorough scrutiny through the implementation of high-precision genotyping methods. Notably, the complex nature of the highly polymorphic CYP2D6 gene necessitates a specialized approach. Our lab utilizes the Hologic Invader assay for genotyping CYP2D6, with the Taqman assay complementing it for the analysis of CYP2D6 copy number variation.

Advanced Techniques

At the UCAT Clinical Laboratory, a range of advanced genotyping techniques is employed, showcasing the institution’s commitment to cutting-edge research practices. Our laboratory employs the QuantStudio 12K Flex Real-Time PCR System, in conjunction with OpenArray custom plates, which enables each genotyping run to yield comprehensive data on up to 480 variants per patient. Notably, due to the intricate nature of the highly polymorphic CYP2D6 gene, a distinct approach is warranted. For CYP2D6 genotyping, the Hologic Invader assay is utilized, allowing for the analysis of 28 star alleles giving physicians an unmatched comprehensive view of the CYP2D6 gene. Finally, The UCAT lab complements the 28 CYP2D6 star allele calls with Copy Number Variation to give a complete look at this very important drug metabolizing gene.

Unveiling Complex Genotypes: Our Story with CYP2D6

Genotyping cytochrome P450, family 2, subfamily D, polypeptide 6 (CYP2D6) is involved in the oxidative metabolism of approximately 20% of all clinically used medications. However, CYP2D6 is a challenge because of the high complexity of the locus.

Our validation of an extensive CYP2D6 assay panel, incorporating Invader and TaqMan Copy Number Variation, contributes significant insights into this complex gene. This research represents an exceptional collaboration between the UCAT Clinical Laboratory and the Center of Personalized Therapeutics (CPT), illuminating new pathways in the realm of genomics.

Robust Evaluation of Custom OpenArray® Pharmacogenomics Panel for Enhanced Clinical Decision-Making.

Pharmacogenomics has the potential to improve patient outcomes through predicting drug response. We designed and evaluated the analytical performance of a custom OpenArray® pharmacogenomics panel targeting 478 single-nucleotide variants (SNVs).

The study employed Coriell Institute cell line DNA samples and whole-blood DNA, comparing genotyping calls to reference methods. The panel demonstrated high concordance and reproducibility for most variants, with only a few exhibiting performance issues. DNA concentration of 50 ng/µL was recommended for optimal genotyping accuracy. The validated panel’s clinically actionable results are employed in pharmacogenomics-based clinical studies for informed decision-making.
