CYP2C9 allele frequency differences between populations of Mexican-Mestizo, Mexican-Tepehuano, and Spaniards

Earlier we had found that the CYP2C9*2 allelic frequency was lower in Mexican-Americans living in California than in Spaniards (SP). This was assumed to be related to the low CYP2C9*2 and *3 allele frequencies in Orientals. This study was therefore aime
