The GSTM1 and GSTT1 null genotype frequencies were significantly different between 658 nonblack and black healthy blood donors from a Brazilian mixed population (Rio de Janeiro). The GSTM1 phenotype distribution was not in Hardy–Weinberg equilibrium in either group, mainly because of an excess of the GSTM1*A/*B genotype.
