  • Title: Placental enzyme polymorphisms in Canadian populations. II. Phosphoglucomutase.
    Author: Donald LJ.
    Journal: Hum Hered; 1977; 27(4):280-4. PubMed ID: 892807.
    Abstract:
    Phenotype distributions and allele frequencies of phosphoglucomatase loci PGM1, PGM2, and PGM3 were determined for four Canadian populations: SWO-Random, a randomly chosen group from southwestern Ontario; SWO-Caucasian, selected from SWO; Indian and Eskimo from the James and Hudson area. In the two population samples from southwestern Ontario, allele frequencies were similar to those of European populations but there was a marked excess of homozygotes at the PGM1 locus. In Indians the PGM1 1 allele had a frequency of 0.922, that of the PGM1 3 allele was 0.765.The allele frequencies for the Eskimo population were 0.848 for PGM1 1 AND 0.884 FOR PGM1 3. One rare phenotype was found at each of the PGM1 AND PGM2 loci.
