In MALDI-TOF MS analysis, (*) 214G>C SNP was used to discriminate gene conversion to CYP2D7P in Intron 1, and (°) 4155C>T SNP was used to discriminate gene conversion to CYP2D7P in Exon 9. A = alanine; R = arginine; N = asparagine; D = aspartic acid; C = cysteine; E = glutamic acide; Q = glutamine; G = glycine; H = histidine; I = isoleucine; L = leucine; K = lysine; M = methionine; F = phenylalanine; P = proline; S = serine; T = threonine; W = tryptophan; Y = tyrosine; V = valine. In bold characters newly discovered SNPs in [5, 17, 18, 21].
