When all tumors were taken together, the presence of the PON1 rs662 (Q192R) variant genotype (RR) was associated with an increased risk of developing embryonal tumors (OR = 2.80, 95 % CI 1.12-7.02).
We investigated whether the polymorphisms PON1 rs662 (Q192R), and PON1 rs854560 (L55M) would be associated with embryonal tumors in Brazilian children.
