We genotyped genes already associated with schistosomiasis in human schistosomiasis genetic literature (IFNG, IL10, IL13, IL4, IL5, STAT6, CTLA4, FCN2, COLEC11, ABO, RNASE3), those in schistosomiasis infection QTL for which we could not find candidate gene studies in the literature (IL17A, IL17B, IL17F, IL6R, IL12B) and some in the Th17 pathway, which is underrepresented in schistosomiasis genetic association studies (IL1A, IL1B, TGFB1, IL6, IL21, IL23A, IL25, IL17RA), as described before [20]. The gene discussed is ABO; the disease is schistosomiasis.
