Several SNPs were associated with susceptibility to infection and septic shock, one in the univariate analysis (rs6853 at MyD88 gene) and seven with the multivariate model (rs610604, rs6922466, rs7753394, and rs583522 at TNFAIP3 gene; rs6579837, rs73272842, rs3792783 at TNIP1 gene). This evidence concerns the gene TNIP1 and infection.
