Polymorphisms in the DDX58 and IFIH1 genes, which code for the retinoic acid inducible gene-1 protein and myeloid differentiation factor (MDA) 5, were investigated in 120 dengue (DEN) cases (88 dengue fever [DF] cases and 32 dengue hemorrhagic fever [DHF] cases) and 109 healthy controls (HCs) to investigate their association with dengue. The results revealed a lower carrier frequency of the DDX58 rs3205166 G allele in DEN than in HCs and a higher frequency of the DDX58 rs669260 T/C genotype in DHF than in DF cases (P = 0.043, OR with 95 % CI 3.358 [1.038-10.861]). This suggests that polymorphisms in DDX58 gene influence the clinical outcome of DENV infection.
