利用等位基因特异扩增法（ＡＳＡ）为基础的基因分型法，对细胞色素Ｐ４５０２Ｄ６（ＣＹＰ２Ｄ６）缺陷型等位基因携带者的９个家庭共３８人进行了基因分型，并与用右旋美沙芬为探针的表型分型法进行对比，发现两种方法的结果是一致的，ＣＹＰ２Ｄ６酶缺陷型等位基因呈常染色体隐性遗传 Using an allele-specific amplification (ASA) -based genotyping method, 38 families of 9 families with CYP2D6-deficient alleles were genotyped and compared with right The comparison of the phenotypic typing of probe with probenecid showed that the results of the two methods were consistent, and the CYP2D6-deficient allele was autosomal recessive
