Abstract
ERAP1 single nucleotide polymorphisms (SNP) are associated with ankylosing spondylitis. Data on ERAP1SNPs in juvenile idiopathic arthritis (JIA) is scarce. ERAP1 rs30187 SNP was shown to confer risk in the enthesitis-related arthritis (ERA) category of JIA. We examined the prevalence and association of this SNP in Indian children with ERA. SNPs in ERAP1 (rs30187) were genotyped in children with ERA (n = 271), ankylosing spondylitis (AS) (n = 213) and healthy controls (n = 101), using Taqman genotyping. Allele frequencies and genotype frequencies were calculated and compared using the Cochran Armitage test. Minor allele frequencies were 0.52 in ERA, 0.57 in AS, and 0.57 in healthy controls. Neither ERA nor AS patients showed significant association with this SNP. Segregating according to HLAB27 status did not alter the lack of association. rs30187 SNP in ERAP1 does not confer risk of developing ERA or AS in the Asian Indian population.
