The lack of associations between the IL17A rs2275913, IL10 rs1800871, IL10 rs1800872, CD209 rs2287886, and CD209 rs4804803 alleles or genotype frequencies with the schistosomiasis clinical manifestations in this population could be due to small sample size, and further studies are necessary to rule out the influence of these SNPs in schistosomiasis pathogenesis. This evidence concerns the gene CD209 and schistosomiasis.
