Rapid Allele-Specific PCR method for CDA 79AÂ >Â C (K27Q) genotyping: A useful pharmacogenetic tool and world-wide polymorphism distribution

► We developed a novel Allele-Specific PCR method for CDA rs2072671 genotyping. ► CDA rs2072671 was genotyped in 324 healthy individuals (Italian and Chinese Han). ► The world-wide distribution of the CDA rs2072671 SNP is reported. ► A striking difference is present among main ethnicities (p = 1.715 x 10-77).
