Inter-individual variations in the genes encoding xenobiotic-metabolizing enzymes have been reported to alter susceptibility to various diseases involving hematological disorders. The purpose of this case-control study was to investigate the relationship between CYP2D6*4 and GSTP1 Ile105Val polymorphisms and the risk of developing BCR-ABL1 negative myeloproliferative neoplasms (MPN). PCR-RFLP was used for genotyping single nucleotide polymorphisms (SNP) in CYP2D6 and GSTP1 in 139 patients with MPN and 126 controls. There was a significantly increased risk for developing BCR-ABL1 negative MPN for the group bearing the CYP2D6*4 variant allele (X2: 4.487; OR 1.738; 95% CI 1.040-2.904; p = 0.034). The platelet count was higher in CYP2D6*4 allele carriers (p = 0.047). There was no association between the GSTP1 Ile105Val polymorphism and the risk of developing MPNs. MPN patients bearing the GSTP1 Ile105Val variant allele had a higher prevalence of bleeding complications (X2: 7.510; OR 4.635; 95% CI 1.466-14.650; p = 0.006). Our study provides new data that the CYP2D6*4 polymorphism may be associated with an increased risk to develop MPNs while the GSTP1 Ile105Val polymorphism does not show such an association. To our knowledge, the current study is the first to investigate the relationship between CYP2D6*4 and GSTP1 Ile105Val polymorphisms and the risk of developing MPNs in the Turkish population. Further studies with more patients and controls are needed to support our data.
