A genome-wide association study in 10,000 individuals links plasma N-glycome to liver disease and anti-inflammatory proteins.

ABSTRACT: More than a half of plasma proteins are N-glycosylated. Most of them are synthesized, glycosylated, and secreted to the bloodstream by liver and lymphoid tissues. While associations with N-glycosylation are implicated in the rising number of liver, cardiometabolic, and immune diseases, little is known about the genetic regulation of this process. Here, we performed the largest genome-wide association study of N-glycosylation of the blood plasma proteome in 10,000 individuals. We doubled the number of genetic loci known to be associated with blood N-glycosylation by identifying 16 novel loci and prioritizing 13 novel genes contributing to N-glycosylation. Among these were the GCKR, TRIB1, HP, SERPINA1 and CFH genes. These genes are predominantly expressed in the liver and show a previously
