Methods Generalized multifactor dimensionality reduction method were utilized to identify the most informative interactions between four SNPs in the TLR4 gene and abdominal obesity. Logistic regression was employed to investigate the association between 4 SNPs within TLR4 gene and OC risk, and additional SNP-SNP and gene-AO interaction on OC risk, ORs (95%CI) were calculated.  \nResults The analysis of logistic regression indicated a markedly elevated risk of OC in individuals carrying either the rs4986790-G or rs11536889-C alleles in the TLR4 gene compared to those with the standard genetic variations, adjusted ORs (95%CI) were 1.61 (1 .28–1. 96) and 1.48 (1 .09–1. 91) . GMDR analysis indicated a significant two-locus model (p = 0 . 018) involving rs4986790 and rs11536889, and a significant two-locus model (p = 0 . 001) involving rs4986790 and AO. Participants with rs4986790-AG/GG and rs11536889GC/ CC genotype has the highest OC risk, compared to participants with rs4986790-AA and rs11536889-GG genotype, OR (95%CI) = 2.58 (1 .46–3. 71), and abdominal obese participants with rs4986790-AG/GG genotype have the highest OC risk, compared to nonabdominal obese participants with rs4986790-AA genotype, OR (95%CI) = 3.17 (1 .78–4. 58) .  \nConclusions The findings suggested that TLR4 gene rs4986790 and rs11536889 polymorphisms were associated with increased OC risk. Significant interaction also existed between rs4986790 and AO, which means that the WC levels may influence the impact of rs4986790 on OC risk.  \nKeywords Abdominal obesity, Ovarian cancer, Single nucleotide polymorphisms, Toll-like receptors, Interaction  \n*Correspondence:  \nCheng Tan  \n[tanchengtc686@163.com](tanchengtc686@163.com)  \n1Department of Oncology, the Affiliated Jiangyin Hospital of Nantong University, Jiangyin city 214400, Jiangsu Province, China 2Department of Radiotherapy, Nantong Tumor Hospital, Tumor Hospital Affiliated to Nantong University, 30 Tongyang North Road, Pingchao Town, Tongzhou District, Nantong City 226300, Jiangsu Province, China  \n© The Author(s) 2025.
