<b>Results </b>Comparison between TBE patients and CG showed that in SNP rs2287886 CD 209 AG heterozygotes were more frequent in the TBE group, while homozygotes GG were more frequent in the CG group.
Thus, our results suggest that the CD209 gene promoter region rs2287886 SNP is associated with predisposition to severe forms of TBE in the Russian population.
