Genetic variants in five novel loci including CFB and CD40 predispose to chronic hepatitis B
AssociationN=6,033Jiang DK et al.(2015)· Hepatology

A genome-wide association study of 83 plasma proteins relevant to cardiovascular disease in 3,394 European subjects identified 79 genome-wide significant loci (p<5e-8), with 55 replicating in independent cohorts (n=2,639). Using eQTL analysis and network methods, the authors proposed plausible causal mechanisms for 25 trans-acting loci including post-translational regulation of KITLG by MMP9 and several receptor-ligand pairs. Multiple loci showed evidence of causal association with coronary artery disease risk.

About FUT2

This gene is one of two encoding the galactoside 2-L-fucosyltransferase enzyme. The encoded protein is important for the final step in the soluble ABO blood group antigen synthesis pathway. It is also involved in cell-cell interaction, cell surface expression, and cell proliferation. Mutations in this gene are a cause of the H-Bombay blood group where red blood cells lack the H antigen.
