TNFSF15 and leprosy: The A allele of rs6478109, which was associated with risk for CD, and protection for leprosy, associated strongly with increased levels of TNFSF15. Additionally, rs4979462 also showed an eQTL effect on TNFSF15 in whole blood (P = 1.19 × 10−4), however this effect was abolished when conditioning on the effect of rs6478109 (Pconditional = 0.692), while the eQTL effect of rs6478109 remained strong after conditioning on rs4979462 (Pconditional = 1.11 × 10−9, Table S6).
