Enzyme polymorphism in placentae from northern Greece

Variations at the PGM1, GOTm, GOTs, and EsD loci were studied in placental samples from Northern Greece. The gene frequencies of GOTm and GOTs were found to be comparable with frequencies reported in other Caucasian populations. The frequencies of the EsD and PGMa11 alleles, however, were lower in Northern Greece than in other European populations.
