- Abstract
Dendritic cell specific intercellular adhesion molecule 3 grabbing non-integrin, coded by the CD209 gene, acts as an entry receptor for dengue virus. 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. Results revealed a significantly higher frequency of 'G' allele and 'G/G' genotype of rs2287886 and A-A-G haplotype of CD209 gene in DEN compared to healthy controls [For 'G/G' genotype, P=0.0072, Odds ratio (OR) 2.43; For A-A-G haplotype, P=0.0033, OR 2]. The frequency of A/A genotype of rs735239 was higher in DEN cases with thrombocytopenia compared to cases without thrombocytopenia (P=0.026). 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., (Copyright © 2013 Elsevier B.V.
