Rs1050152

rs1050152, a SNP in the SLC22A4 gene known as L503F, has been associated with an autoimmune disease, in this case, Crohn's disease, odds ratio = 2.1 (CI = 1.31â€“3.39, p = 0.002), based on a study of 203 cases and 200 controls. The risk allele is rs1050152(T).

A nearby SNP (rs2631367) in the promoter region of the SLC22A5 gene defines a haplotype along with rs3792876, with odds ratio reported as similar for either SNP or the haplotype. Referring to the TC risk haplotype, the population risk attributable to heterozygotes was 19%, and for homozygous haplotype carriers, 27%.
