摘要: 作者用超薄层聚丙烯酰胺凝胶等电聚焦技术,调查了204名西茂地区无血缘关系藏族个体血清α1-抗胰蛋白酶(Pi)的表型,除检出6种常见PiM亚型外,还检出了4种变异型。其中,1种是国内外尚未见报道的新的Pi变异型,1种是缺陷型,其血清Pi相对含量为69.51%。推算出Pi等位基因频率为:PiM1=0.7624,PIM2=0.1634,PiM3=0.0668和PiV=0.0074。
The distribution of subtypes and gene frequencies ofα1-antitrypsin were studied in 204 unrelated healthy blood donors in Tibetan population in Tibet using ULPAGIF.Besides six common PiM subtypes,four kinds of Pi variants were detected.They were as follows:PiM1/L,R,M1-and a new variant.The relative concentration of M1-was 69.51%.The gene frequencies of Pi alleles were PiM1=0.7624,PiM2=0.1634,PiM3= 0.0668,PiV=0.0074.
