title: Alpha 1-antitrypsin phenotypes in Canadian Metis.
abstract: Alpha 1-antitrypsin phenotyping was performed on serum of 344 Metis living in an isolated northern Saskatchewan community. Only PiM and PiMZ phenotypes were observed with phenotype frequencies of 98.5 and 1.5 respectively. Gene frequencies were 0.993 for PiM and 0.007 for PiZ. The low frequency of non-M phenotypes is similar to that in another population of North American natives, the Eskimos of Igloolik as well as Finnish and Norwegian Lapps.
