PGM3 polymorphism in human placenta samples from Bahia, Brazil

PGM3 polymorphism was studied in 301 placenta samples from the Negroid population of Northeastern Brazil. The following gene frequencies were encountered: PGM3*1 = 0.545 and PGM3*2 = 0.455. They lie between European and African gene frequencies. The prevalent Black and White admixture of Northeastern Brazil populations fits well with the observed gene frequencies. Two samples exhibited variant electrophoretic patterns.
