    Abstract:
    FCGR2A and CCL2 gene variants are important in dengue pathogenesis and were investigated in 122 dengue patients (DENs) [89 dengue fever (DF) and 33 dengue hemorrhagic fever (DHF)] and 107 healthy controls (HCs) to find out their association with severity of dengue. Genotype frequencies of FCGR2A p.R131H and CCL2 c.-2518 A > G polymorphisms were not different between DF, DHF and HC. Significantly higher frequency of R/R genotype of FCGR2A p.R131H was observed in DEN cases with thrombocytopenia (TP) while the G/G genotype of CCL2 c.-2518 A > G was observed only in DEN cases with TP (p < 0.005). These results suggest that FCGR2A and CCL2 gene variants were associated with the risk of TP in dengue infections.
