Abstract

The same viral infection in different hosts may result in varying levels of clinical symptoms, which is related to the genetic background of the host itself. A total of 406 common cases and 452 severe cases of enterovirus 71 (EV71) infection in Yunnan Province were selected as the research subjects, and SNaPshot technology was used to detect genetic polymorphisms for 25 Tag single-nucleotide polymorphisms (TagSNPs) in the selectin P ligand (SELPLG) and scavenger receptor class B member 2 (SCARB2) genes. Our results demonstrate that SCARB2 polymorphisms (rs74719289, rs3733255 and rs17001551) are related to the severity of EV71 infection (A vs G: OR 0.330; 95% CI 0.115 - 0.947; T vs C: OR 0.336; 95% CI 0.118 - 0.958; and A vs G: OR 0.378; 95% CI 0.145 - 0.984). The SELPLG polymorphisms were not significantly different between common cases and severe cases. Therefore, we conclude that the SCARB2 gene has a protective effect on the course of hand, foot and mouth disease caused by EV71 infection and that SCARB2 gene mutations can reduce the severity of the disease.
