For the first time the distribution frequency of C677T methylenetetrahydrofolate reductase (MTHFR) genotypes was detected in a limited part of Ukrainian population. Cytosolic activity in human placenta samples with different allelic gene variants of MTHFR in combinations with polymorphic genes of glutathione S-transferase P1, glutathione S-transferase M1, and cytochrome P450 1A1 was analyzed. The substitution of C677→T677 in at least one allele of MTHFR gene is accompanied by the tendency of GST activity to increase. The tendency remains irrespectively of other allelic gene variants combination. The possible relation between the MTHFR allelic variants and cytosolic glutathione S-transferase activity is discussed.

Key words: polymorphism of methylenetetrahydrofolate reductase, glutathione S-transferase P1 and M1, human placenta, glutathione S-transferase activity.
