Background and tumour necrosis factor-alpha (TNF-α). Methods A total of 250 women volunteered for the study; of which 100 were diagnosed with PCOS and 150 were healthy controls. Serum levels of IL-6, IL-1β, and TNF-α were measured using enzyme-linked immunosorbent assay (ELISA). Genotyping was analysed using polymerase chain reaction (PCR), PCR-restriction fragment length polymorphism (PCR-RFLP), or real-time PCR (RT-PCR). Genotype distributions amid groups were compared using the Chi-square test. Results Women with PCOS exhibited elevated serum levels of IL-1β than those of healthy controls which was considerably significant ( P <0.001). The heterozygous genotypes of IL-1 RN and IL-6 rs1800796 were seen more frequently in the control group ( P =0.02), suggesting a potential inverse association. Interpretation & conclusions SNPs in IL-1 and IL-6 genes may influence susceptibility to PCOS and could confer a protective role in women of South Asian Indian origin.
