Abstract

<jats:p> Aims: Members of the ATP-binding-cassette transporter family are implicated in the traffic of drugs/xenobiotics. Several SNPs in these ATP-binding-cassette genes were previously identified to show evidence of recent positive selection. These recent positive selection SNPs may confer functional effects and account for variation in drug response. To facilitate association studies between these SNPs and drug response, we report the development of a homogeneous (realtime exonuclease-mediated allelic discrimination) assay to genotype these SNPs. Materials &amp; methods: Realtime exonuclease-mediated allelic discrimination involves real-time PCR using a proof-reading enzyme and simultaneous genotype determination by product presence/absence as detected using SYBR<jats:sup>®</jats:sup> Green I stain. Results: A total of 29 recent positive selection SNPs from 17 ATP-binding-cassette transporter genes were evaluated. Of the 777 eealtime exonuclease-mediated allelic discrimination assays, 773 genotypes (∼99.5%) were concordant with the Perlegen data and other genotyping methods. Conclusion: Therefore, this simple, robust, rapid, cost-effective single-step, closed-tube assay with a scalable and automatable platform has potential applications in population genetic screening and association studies. </jats:p>
