Among significant associations found between virus infections and genetic variants, we report for the first time an association of rs4804803 (CD209) A and G variants with susceptibility to HBV infection and spontaneous clearance (p<0.001, OR=3.53, 95% CI 2.155; 5.908, and p<0.001, OR=7.75, 95% CI 4.646-13.114, respectively).
In the early events of human immunodeficiency virus type 1 (HIV-1) infection, immature dendritic cells (DCs) expressing the DC-specific intercellular adhesion molecule 3-grabbing nonintegrin (DC-SIGN) receptor capture small amounts of HIV-1 on mucosal surfaces and spread viral infection to CD4(+) T cells in lymph nodes (22, 34, 45).
Previously the severity and outcome of dengue fever and hepatitis C (diseases caused by viruses from the family Flaviviridae) were associated with the rs4804803 single nucleotide polymorphism (SNP) located in the promoter region of the human CD209 gene.
