Abstract

Dengue virus (DENV) is currently considered as one of the most important mosquito-borne viral pathogens affecting humans. Genetic variations in viruses are likely to be a condition for more effective evasion of the immune system and resulting in severe clinical consequences. The DENV‑1 NS5 gene was sequenced to establish whether during an epidemic burst there were genetic variations of the virus and whether any variant was associated (through a case‑control design) with severe clinical behavior. A total of 31 patients positive for DENV‑1 were enrolled. Among the nucleotide differences between the sequences, only two generated amino acid changes. The variants 124Met/166Ser (amino acid positions according to the report GenBank AJL35015.1), were associated with a severe clinical course of the disease. Via in silico tests, it was identified that the variations generate changes in the protein probably affecting the function of type‑1 interferon, either at the level of its receptor or by interfering with the Janus kinase‑signal transducer and activator of transcription signaling pathway.
