Is there still room for additional common susceptibility alleles for venous thromboembolism

Background Through a meta-analysis of 12 genome-wide association studies, the International Network against VENous Thrombosis (INVENT) consortium identified two novel susceptibility loci for venous thromboembolism (VTE). This project has also generated other candidates that need to be confirmed. Objectives To assess the association with VTE of common single-nucleotide polymorphisms (SNPs) that demonstrated strong statistical, but not genome-wide, significance in the INVENT cohorts. Patients/methods Eleven SNPs were genotyped and tested for association with VTE in three case–control studies totaling 3019 patients and 2605 healthy individuals. Results and conclusions None of the tested SNPs showed evidence for association with VTE. Different strategies are needed to decipher the whole spectrum of common and rare genetic variations associated with VTE risk.
