Rs4810485-T (CD40 locus) was associated with multiple autoimmune disorders, including “rheumatoid arthritis” (OR = 0.85, p = 5.7 × 10−9), “inflammatory bowel disease” (OR = 1.08, p = 4.6 × 10−10) and “multiple sclerosis” (OR = 1.08, p = 1.8 × 10−5). This evidence concerns the gene CD40 and multiple sclerosis.
