| Popis: | Developing genetic and pharmacogenetic panels enhances genetic testing in clinical molecular diagnostics and precision medicine. This study was designed to cross-validate the performance of Canon's multiplex high-resolution DNA melting analysis platform with the Applied Biosystems TaqManGenomic DNA isolated from 240 blood and saliva samples was used to genotype the VKORC1-1639 G/A (rs9923231), CYP2C9*2 (430CT, rs28371674), and CYP2C9*3 (1075AC, rs1057910) single-nucleotide polymorphisms (SNPs) on the three above-mentioned genotyping platforms.There was 99.2%, 100%, and 100% concordance among the Canon DNA analyzer, the TaqMan-based QuantStudio, and the Pyrosequencing genotyping results for the VKORC1 (rs9923231), CYP2C9*2, and CYP2C9*3 SNPs, respectively, in DNA samples isolated from blood. The DNA samples isolated from saliva showed 100% concordance among the three test platforms for the three tested SNPs.These results show that, the DNA analyzer performed very well when compared with two commonly used genotyping platforms. The reliability, multiple genetic variant testing capability, and short turnaround time for up to eight samples make the DNA analyzer an ideal genotyping platform for genetic testing in the clinical practice setting, where efficient genotyping is important to prevent delays in optimizing drug therapy. |
