We assessed the association of these SNP with AS in a Spanish population. Methods Four hundred fifty-six patients with AS fulfilling the modified New York Criteria and 300 healthy donors were analyzed. Results SNP rs10865331 (allele A: p = 0.039; genotype: p = 0.016) was significantly associated with AS, while no association was found for rs2242944. Conclusion This is the first study that replicates in an independent cohort the association of the intergenic SNP rs10865331 with susceptibility to AS.
