PHF19 and influenza: Similarly, in a comparable study of stimulation-specific eQTLs in dendritic cells derived from peripheral blood monocytes of 534 individuals, the RA-susceptible variant rs881375 in the intergenic TRAF1-PHF19 region (R2 = 0.902, D’ = 1.000 with rs7021880) showed response eQTL after LPS and influenza stimulation (respectively P = 6.33 × 10−8 and 1.04 × 10−10) [26].
