Antitrypsin phenotypes were determined from 2,285 donors at the Barnes Hospital Blood Bank in St. Louis . Results resembled those obtained from Central Europeans: there were fewer proteinase inhibitor (Pi) Z alleles in St. Louis than in Scandinavian test groups. Interestingly, major antifrypsin variants occurred only 40% as frequently in black as in the balance of the study group.
在圣路易斯的巴恩斯医院血库,对2285名献血者进行了抗胰蛋白酶表型测定。结果与从中欧人群中获得的结果相似:圣路易斯的蛋白酶抑制剂(Pi)Z等位基因比斯堪的纳维亚测试组中的要少。有趣的是,主要的抗胰蛋白酶变体在黑人中的出现频率仅为研究组其他人群的40%。
