Single nucleotide polymorphisms in immune system genes and their association with clinical symptoms persistence in dengue-infected persons.

This study was undertaken to determine the prevalence of dengue clinical symptom persistence during 60days of disease follow up, in patients of Espírito Santo state (ES)-Brazil and to evaluate the relation of single nucleotide polymorphisms (SNPs) in FcγRIIa, CD209, VDR, TNF-α, IL-4, IL-6 and IFN-γ genes with symptom persistence. During 2012-2013, 96 blood samples from individuals diagnosed with symptomatic dengue were collected.
