This investigation also found no association between the IL17A rs7747909 G>A 3’ UTR SNV and Chagas cardiopathy and between two other IL17A promoter SNVs (rs4711998 and rs3819024) or IL17A rs2275913 and heart disease, in a context where the latter A allele is associated with increased IL17 A levels (40, 41). This evidence concerns the gene IL17A and heart disorder.
