Abstract
OBJECTIVE: To study the association between single-nucleotide polymorphism (SNP) of long-chain non-coding RNA steroid receptor RNA activator (lncRNA SRA1) gene and polycystic ovary syndrome (PCOS) susceptibility. METHODS: Sanger sequencing was used to analyze the genotypes of the lncRNA SRA1 gene rs801460, rs10463297, and rs250426 in 315 PCOS patients and 315 control groups. RESULTS: There was no correlation between lncRNA SRA1 gene rs801460, rs250426 SNP, and PCOS susceptibility (p > 0.05). The T allele at the rs10463297 locus of the SRA1 gene has a lower risk of PCOS than the C allele (OR = 0.63, 95%CI: 0.50-0.79, p < 0.01). Among people with a BMI ≥ 26.5 kg/m2, when carrying the TC genotype and CC genotype at rs801460, the risk of PCOS susceptibility was lower than the TT genotype (OR = 0.54, 95%CI: 0.33-0.89, p = 0.02). At different ages and BMI stratifications, there was a significant association between rs10463297 SNP and PCOS susceptibility (p < 0.05). Multi-factor dimensionality reduction (MDR) analysis results showed that age, BMI, rs801460, rs10463297, and rs250426 interactions constitute a "high-risk combination." PCOS susceptibility risk was 5.96 times that of a "low-risk combination" (95%CI: 4.14-8.56, p < 0.01). SRA1 gene rs801460, rs10463297, rs250426 constructed TCT haplotype was associated with increased risk of PCOS susceptibility (OR = 1.66, 95%CI: 1.20-2.30, p < 0.01); the CTT haplotype was associated with a decreased risk of PCOS susceptibility (OR = 0.56, 95%CI: 0.36-0.87, p = 0.01). LncRNA SRA1 gene rs10463297 SNP was correlated with the level of lncRNA SRA1 in the peripheral blood leukocytes (p < 0.01). CONCLUSION: From this study, we found that the lncRNA SRA1 gene rs10463297 SNP is associated with PCOS susceptibility.
