Antitrypsin phenotypes in St. Louis
J. A. Pierce, B. Eradio and T. A. Dew
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.
