A new rare variant of the glyoxalase I system of the red cell: GLO-Sicily

A fast variant of the red cell enzyme glyoxalase I was identified in a sample of 663 persons from Eastern Sicily; the allele was designated GLOSi. The gene frequencies for the common alleles GLO1 and GLO2 are not different from those observed in other southern Italian populations, and are in agreement with the hypothesis of a westward gene flow from Asia.
