Objective Recently, the FCRL3 ?69T>C (rs7528684) single-nucleotide polymorphism (SNP) has been demonstrated to be a risk factor of endometriosis related infertility. We studied whether the FCRL ?69T>C SNP can be associated with endometriosis-related infertility in a sample of the Polish population Methods Using PCR–RFLP analysis we genotyped 141 infertile women with endometriosis and 519 fertile women. FCRL3 transcript levels were determined by reverse transcription and real-time quantitative PCR analysis in CD19+ B cells from women with endometriosis-associated infertility and fertile women Results We found a significantly increased frequency of the FCRL3 C/C genotype in women with endometriosis-associated infertility than controls [OR?=?1.681 (95?% CI?=?1.120-.522, p?=?0.0116, p corr?=?0.0348)]. There was also a statistically increased frequency of the C/C and C/T genotypes in patients compared with controls [OR?=?2.009 (95?% CI?=?1.214-.324, p?=?0.0059, p corr?=?0.0177)]. The p value of the χ 2 test for the trend observed for the FCRL3 ?69T>C polymorphism was also statistically significant (p trend?=?0.0012, p corr?=?0.0036). We also found significantly increased FCRL3 transcript levels in carriers of the FCRL3 ?69 CC vs TT and CT vs TT genotype both in women with endometriosis-related infertility (p?=?0.012; p?=?0.015) and fertile women (p?=?0.017; p?=?0.032) Conclusions FCRL3 ?69T>C polymorphism alters the expression of FCRL3 and can be a risk factor of endometriosis-related infertility.
