Polymorphisms:GSTO1*A140D (C419A; rs4925), GSTO2*N142D (A424G; rs156697)Main findings:- reduced risk of human papillomavirus (HPV) 6, 16, 18, and 16/18 infections and CC in subjects with GSTO1*D140 variant (GSTO1*A allele; rs4925), heterozygous GSTO1*A140D (*C/*A genotype), and the combination of heterozygous GSTO1*A140D (140AD) and homozygous wild-type GSTO2*N142 (142NN);no association between GSTO2*N142D polymorphism and HPV infections and cervical cancer. The gene discussed is GSTO2; the disease is cervical carcinoma.
