A common variant in PIK3CG gene associated with the prognosis of heart failure.

ABSTRACT: Phosphoinositide 3-kinase γ (PI3Kγ) is G-protein-coupled receptor-activated lipid kinase with both kinase-dependent and kinase-independent activity. Plenty of evidence have demonstrated that PI3Kγ participated in TAC and I/R-induced myocardial remodelling and heart failure (HF). In this study, we tested the hypothesis that common variants in the PI3Kγ gene (PIK3CG) were associated with the prognosis of HF in the Chinese Han population. Through re-sequencing and genotyping, we finally identified a common variant in the 3'UTR of PIK3CG strongly associated with the prognosis of HF in two-stage population: adjusted p = 0.007, hazard ratio = 0.56 (0.36-0.85) in the first cohort and adjusted p = 0.024, hazard ratio = 0.39 (0.17-0.88) in the replicated cohort. A series of functional assays reveal
