TLR10 and NFKBIA contributed to the risk of hip osteoarthritis: systematic evaluation based on Han Chinese population.

Multiple lines of evidence have confirmed the importance of genetic factors for hip osteoarthritis (HOA). Our study aimed to investigate the associations of TLR10 and NFKBIA with respect to the HOA risk in Han Chinese individuals. A total of 1,043 HOA patients and 2,664 controls were recruited. Then, 23 tag single-nucleotide polymorphisms (SNPs) in the TLR10 and NFKBIA genes were selected for genotyping. Genetic association analyses were conducted in both single-marker and haplotype-based ways. Gene by gene, two-way interactions were analysed using a case-only method. Multiple bioinformatics tools were utilised to examine the potential functional significance of the SNPs. Two significant SNPs, rs11096957 (OR = 1.26, P = 1.35 × 10^-5) and rs2273650 (OR = 1.2, P = 1.57 × 10^-3), were significantly associated with HOA risk. Rs11096957 was also associated with the severity of the HOA. Bioinformatics analysis indicated that the allele T of rs2273650 would create new miRNA/SNP target duplexes, which suggests that rs2273650 could alter the NFKBIA expression by affecting the miRNA/SNP target duplexes. Our study identified significant association signals from NFKBIA with HOA for the first time, and it also confirmed the contribution of TLR10 to the HOA risk. These findings would provide clues for identifying individuals at high risk of HOA.
