This study is to investigate the relationship of programmed cell death 1 (PD-1; also known as PDCD1) and programmed death-1-ligand 1 (PD-L1; also known as CD274) single nucleotide polymorphisms (SNPs) with polycystic ovary syndrome (PCOS). This study enrolled 330 PCOS patients and 350 matched controls. ELISA was used to detect the PD-1 and PD-L1 levels in serum. SnaPshot genotyping was performed to analyze the PD-1 and PD-L1 genotyping. Linkage disequilibrium and haplotype of TagSNP loci of PD-1 and PD-L1 genes were also detected. The relationship of genotypes and alleles with PCOS was analyzed. The levels of PD-1 and PD-L1 in the serum of PCOS patients were significantly lower than those in the control group ( < 0.01). The haplotype TT of PD-1 gene at rs10204525 and rs7421861 loci was significantly lower in the PCOS group than in the control group ( < 0.001, OR = 0.67, and 95%CI = 0.54-0.84). PD-L1 gene SNP loci rs2282055, rs2890658, rs10125854, and rs702275 had linkage disequilibrium. The haplotypes TAAA, GAAC, GAGC, GCAA, and TCGA of PD-L1 gene SNP loci were significantly higher in PCOS patients than in the control group, whereas haplotypes GAAA, TAAC, TCAA, GCGA, GCAC, and TCGC of PD-L1 gene SNP loci were significantly lower in PCOS patients than in the control group. PD-1 and PD-L1 SNPs may be related to the pathogenesis of PCOS. PD-1 gene SNP loci rs10204525 and rs7421861 and PD-L1 gene SNP loci rs2282055, rs2890658, rs10125854, and rs702275 may be new candidate polymorphic loci for PCOS.
这项研究旨在探讨程序性细胞死亡 1（PD-1；也称为 PDCD1）和程序性死亡配体 1（PD-L1；也称为 CD274）单核苷酸多态性（SNP）与多囊卵巢综合征（PCOS）的关系。本研究纳入了 330 例 PCOS 患者和 350 例匹配对照。采用 ELISA 法检测血清中 PD-1 和 PD-L1 水平。采用 SnaPshot 基因分型法分析 PD-1 和 PD-L1 基因分型。还检测了 PD-1 和 PD-L1 基因 TagSNP 位点的连锁不平衡和单倍型。分析了基因型和等位基因与 PCOS 的关系。PCOS 患者血清中 PD-1 和 PD-L1 水平明显低于对照组（<0.01）。PD-1 基因 rs10204525 和 rs7421861 位点 TT 单倍型在 PCOS 组明显低于对照组（<0.001，OR=0.67，95%CI=0.54-0.84）。PD-L1 基因 SNP 位点 rs2282055、rs2890658、rs10125854 和 rs702275 存在连锁不平衡。PD-L1 基因 SNP 位点 TAAA、GAAC、GAGC、GCAA 和 TCGA 单倍型在 PCOS 患者中明显高于对照组，而 PD-L1 基因 SNP 位点 GAAA、TAAC、TCAA、GCGA、GCAC 和 TCGC 单倍型在 PCOS 患者中明显低于对照组。PD-1 和 PD-L1 SNP 可能与 PCOS 的发病机制有关。PD-1 基因 SNP 位点 rs10204525 和 rs7421861 以及 PD-L1 基因 SNP 位点 rs2282055、rs2890658、rs10125854 和 rs702275 可能是 PCOS 的新候选多态性位点。
