Linkage disequilibrium and haplotype analyses were conducted to assess the association of the candidate SNPs with disease susceptibility. A cohort of 2,144 AS patients was stratified based on the presence or absence of risk-associated haplotypes and clinical phenotypes\u00a0were compared\u00a0between the two groups. Reverse transcription-polymerase chain reaction (RT-PCR) was employed to quantify mRNA expression levels in peripheral blood mononuclear cells (PBMCs) from 40 AS patients and 32 HCs. Immunohistochemistry (IHC) was utilized to evaluate ANO6 protein expression in tendon tissues from 9 AS patients and 5 control subjects.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Five SNP loci (rs79662606, rs76186361, rs17095830, rs80224086, and rs75712006) exhibited significant associations with AS susceptibility, with strong linkage disequilibrium observed between pairwise loci. Haplotype analysis revealed a higher prevalence of GTGCG, ATGTA, and ACGTA haplotypes in AS patients (p &lt; 0.001). No significant differences in clinical phenotypes were observed between AS patients with or without risk-associated haplotypes. mRNA expression in PBMCs was significantly lower in AS patients (0.49 \u00b1 0.21) compared to HCs (0.86 \u00b1 0.38) (p &lt; 0.001). Conversely, ANO6 protein expression was significantly elevated in tendon tissues of AS patients, with an average Histoscore of 182.22 \u00b1 30.732 compared to 62.00 \u00b1 35.637 in controls (p = 0.001).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>ANO6 may represent a\u00a0novel AS susceptibility gene, with GTGCG, ATGTA, and ACGTA as risk-associated haplotypes.
