Alpha-1-antitrypsin phenotypes of umbilical cord serum from 741 Polish newborns were studied by isoelectric focusing. The frequencies of the PI alleles were: PI*M1 = 0.7199, PI*M2 = 0.1613, PI*M3 = 0.0965, PI*S = 0.0094, PI*Z = 0.0067, and PI*Var(F,I,L) = 0.0060. The data obtained for Poland were compared to those for other European populations.
