An increase in the frequency of the rs2287886 SNP AA homozygotes and the A allele was detected among patients with severe central nervous system disease compared with the group of patients with meningitis (P=0.003 and 0.019), or a combined group of patients with mild forms (fever and meningitis) (P=0.003 and 0.026), or the control group (P=0.007 and 0.035).
The results suggest that rs2287886 G/G genotype of CD209 gene is associated with development of dengue requiring hospitalization while A/A genotype of rs735239 is associated with thrombocytopenia in dengue cases.
We screened 4 single nucleotide polymorphisms (SNPs) in the promoter region of CD209, namely -939G>A (rs735240), -871A>G (rs735239), -336A>G (rs4804803) and -139G>A (rs2287886) and tandem repeat polymorphisms in exon 4 of CD209 and CD209L genes looking for association with TB in a Northeastern Brazilian population (295 subjects, 131 TB patients and 164 healthy controls).
Data obtained suggest that the OAS2 rs1293762 and CD209 rs2287886 SNPs are associated with predisposition to chronic hepatitis C in Russian population.
CCR2 V64I (G/A), monocyte chemoattractant protein-1 (MCP-1) -2518 A/G, stromal cell derived factor-1alpha; (SDF-1alpha) 3'UTR G/A and DC-SIGN gene polymorphisms were studied by polymerase chain reaction based methods in HIV-1 infected patients without TB (n=151), with pulmonary TB (PTB) (n=81) and extrapulmonary TB (n=31), 155 PTB patients without HIV and 206 healthy controls.

Polymorphisms in the promoter region of CD209 gene (rs735239, rs4804803, rs2287886) were investigated in 112 hospitalized cases of dengue (DEN) and 104 healthy controls to find out whether they are associated with dengue in a Western Indian population.
A single nucleotide polymorphism (SNP) in the promoter region of CD209 (-336 A/G; rs4804803) affects transcription and is associated with the severity of tuberculosis and dengue fever.
Because the -336A/G SNP (rs4804803) polymorphism in the promoter of CD209 modulates DC-SIGN expression, we investigated the putative association of this polymorphism with DENV infection and its pathogenesis.
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).
In this study, real-time PCR was used to characterize the distribution of rs1801274 and rs4804803 in subjects with asymptomatic dengue infection (n=145), uncomplicated dengue (n=67), and severe dengue (n=36) in Morelos.
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.
A single nucleotide polymorphism (SNP) in the promoter region of CD209 (-336 A/G; rs4804803) affects transcription and is associated with the severity of tuberculosis and dengue fever.
A total of 2,176 individuals enrolled in tuberculosis case-control studies from four sub-Saharan Africa countries were genotyped for the CD209 -336A/G SNP (rs4804803).
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).
