Higher mortality on severe sepsis in the discovery and combined cohorts was significantly associated with the CC genotype in a THBD promoter SNP (−1920*C/G; rs2239562) [odds ratio [OR] 2.709 (1.067–6.877), P = 0.033 and OR 1.768 (1.060–2.949), P = 0.028]. The gene discussed is THBD; the disease is Sepsis.
