Genome-wide analysis of polymorphisms associated with cytokine responses in smallpox vaccine recipients
AssociationN=1,000Kennedy RB et al.(2012)· Human Genetics

Genome-wide association study identifying SNPs associated with cytokine responses to vaccinia virus in 1,000 smallpox vaccine recipients. Multiple SNPs achieved genome-wide significance (p<5×10⁻⁷) for Th1 cytokines (IL-2, TNFα, IL-12p40) and inflammatory cytokines (IL-1β, IFNα, IL-6). Notable findings include rs16948200 in NGFR (12-fold difference in IL-2 secretion between genotypes), rs4251424 in IRAK4 (associated with TNFα), and rs2255327 in BLK (2-fold higher IL-6 in heterozygotes).
