Abstract

Data suggests that dopamine receptor DRD2 gene variants may contribute to hyperprolactinemia and that they may be risk factors for endometriosis-related infertility. The purpose of the present study was to determine whether nucleotide variants of the DRD2 gene may be associated with infertility related to endometriosis. Five DRD2 SNPs, rs1800497, rs6277, rs2283265, rs4245146 and rs4648317, which are located in different blocks of linkage disequilibrium, were studied in 151 cases and 381 controls. No significant differences between DRD2 rs1800497, rs6277, rs2283265, rs4245146 and rs4648317 genotype, allele nor haplotype frequencies were observed in women with endometriosis-related infertility compared with the control group. The present results did not confirm DRD2 gene variants to be genetic risk factors for endometriosis-related infertility.
