The functional analysis of the association between other polymorphisms, expression quantitative trait loci (eQTLs), for the CAMKK2, COQ5, P2RX7, and C12orf43 genes in relation to the single-nucleotide polymorphism rs2230912, remains to be conducted to assess its effect on cytokine response in ex vivo models of infection [61]. This evidence concerns the gene COQ5 and infection.
