BackgroundThe 6986A> G polymorphism for CYP3A5 and the −129T> C, 1236C> T, 2677G> T/A, and 3435C> T polymorphisms for MDR1 are considered the major genetic factors affecting a range of drugs' metabolism and transport. Simultaneous genotyping of these five polymorphisms would be useful for estimating the therapeutic effects of their related drugs.Subjects and methodsWe have described a SNaPshot assay that can simultaneously detect all the five polymorphisms based on multiplex PCR and minisequencing reaction. A total of 168 unrelated Chinese DNA samples were used to establish and evaluate the assay.ResultsThe different genotypes of the five polymorphisms could be determined by peak retention time and colors. DNA sequencing was performed on samples randomly selected from each of the genotype groups detected by SNaPshot assay, and the results indicated 100% concordance.ConclusionThe SNaPshot assay for the CYP3A5 and MDR1 five polymorphisms detection was accurate, automated, and cost-effective.
