Gene Polymorphism of Xenobiotic Biotransformation Enzymes in Patients with Classical Ph-Negative Myeloproliferative Neoplasms

Abstract

The correlation of gene polymorphisms rs4025935 (large deletion), rs1695 (313A>G), rs71748309 (large deletion), and rs1800566 (609C>T) of GSTM1, GSTT1, and NQO1 genes encoding glutathione-S-transferases (GST) M1, P1, and T1 and NADPH-quinone oxidoreductase with the risk of development of classical Ph-negative myeloproliferative neoplasms (polycythemia vera, essential thrombocythemia, and primary myelofibrosis) was studied in the Caucasian ethnicity population of Vyatka region of the Russian Federation. It was found that NQO1*609T allele, NQO1*609T genotypes, and homozygous carriage of a deletion (null) allele of GSTT1 gene are associated with the risk of development of myeloproliferative neoplasms (OR=1.29, 95%CI=1.02-1.64, p=0.04; OR=1.39, 95%CI=1.04-1.85, p=0.03; and OR=1.48, 95%CI=1.03-2.12, p=0.03, respectively). However, no influence of GSTM1 and GSTP1 gene polymorphisms on the risk of development of myeloproliferative disorders was registered.
