<i>Conclusions</i>: Dendritic cell-specific intercellular adhesion molecule-3-grabbing non-integrin (<i>DC-SIGN</i>) promoter-336G/A (<i>rs4804803</i>) polymorphism is association with severe dengue, and it acts in different directions for Asians and South-central Americans.
HLA-A-specific epitopes were predicted from binding motifs, and ELISPOT analyses of patients with DHF revealed high frequencies of circulating CD8 T lymphocytes that recognized both serotype-specific and -cross-reactive dengue virus epitopes.
IL1B -31C and IL1RA 2/4 genotype were associated with DSS (IL1B -31C: DSS vs DHF: P = .0061, odds ratio [OR, 95% confidence interval {CI}], 3.49 [1.36-8.95]; DSS vs DF: P = .027, OR [95% CI], 2.81 [1.12-7.06]; IL1RA 2/4: DSS vs DHF: P = .017, OR [95% CI], 1.94 [1.12-3.40]; DSS vs DF: P = .024, OR [95% CI], 1.90 [1.07-3.4]).
IL-1β is a potent inflammatory cytokine that is frequently elevated during severe dengue, and the unique dual regulation of IL-1β provides an informative model to study ADE-induced cytokines.
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.
A combination of TNF-α -308GA+AA genotype and IL-10 non-GCC haplotypes, IL-12B pro homozygotes (pro1/pro1, pro2/pro2) and IL-12B 3'UTR AC were significantly correlated with protective effects against DHF/DSS.

A common CD209-336G/A (rs4804803) polymorphism in DC-SIGN may affect severity of dengue virus infection (DEN) and incidence of dengue fever (DF) or the more severe dengue hemorrhagic fever (DHF).
A previous genome-wide association study identified 2 susceptibility loci for severe dengue at MICBrs3132468 and PLCE1 rs3740360 and further work showed these mutations to be also associated with less severe clinical presentations.

A protective association among the IFNG (+874 A/T) A/T genotype against DF (P = 0.02, OR = 0.46, CI = 0.24-0.89) and DHF (P = 0.034, OR = 0.43, CI = 0.19-0.95) was observed.
A sequencing-based typing method and genotyping of MICA and MICB in a well-characterized group of Cuban individuals with dengue hemorrhagic fever (DHF), dengue fever (DF), or asymptomatic dengue infection (ADI) was performed.

A striking correlation was observed between increased levels of IL-8 and severe DHF, with greater levels in patients with increased grade of the disease and death.
Alpha tryptase allele of Tryptase 1 (TPSAB1) gene associated with Dengue Hemorrhagic Fever (DHF) and Dengue Shock Syndrome (DSS) in Vietnam and Philippines.
