A follow-up study of a genome-wide association scan identifies a susceptibility locus for venous thrombosis on chromosome 6p24.1.

International audience; To identify genetic susceptibility factors conferring increased risk of venous thrombosis (VT), we conducted a multistage study, following results of a previously published GWAS that failed to detect loci for developing VT. Using a collection of 5862 cases with VT and 7112 healthy controls, we identified the HIVEP1 locus on chromosome 6p24.1 as a susceptibility locus for VT. Indeed, the HIVEP1 rs169713C allele was associated with an increased risk for VT, with an odds ratio of 1.20 (95% confidence interval 1.13-1.27, p = 2.86 x 10(-9)). HIVEP1 codes for a protein that participates in the transcriptional regulation of inflammatory target genes by binding specific DNA …

A029 Identification of polymorphisms in the gene encoding secreted phospholipase A2 group X and study of their role in coronary artery disease. The atherogene study

Human secreted phospholipases A2 (sPLA2s) represent novel attractive therapeutic targets and biomarkers in coronary artery diseases (CAD). We have shown that human Group X sPLA2 (hGX sPLA2) is present in atherosclerotic lesions and that hGX sPLA2 modified LDL induces foam cell formation. To elucidate whether hGX sPLA2 has a causative role in CAD we have screened the human PLA2G10 gene to identify frequent polymorphisms, and we have examined their possible association with cardiovascular end-points and intermediate inflammatory phenotypes in a large prospective study of patients with CAD (the AtheroGene study). Although no significant association was found between the various polymorphisms i…

Plasma PAF-acetylhydrolase in patients with coronary artery disease: results of a cross-sectional analysis.

Inflammation underlies both onset and perpetuation of atherosclerosis. Plasma lipoproteins transport the platelet-activating factor-acetylhydrolase (PAF-AH) with potentially anti-inflammatory activities. Our aim was to determine whether PAF-AH activity was associated with inflammatory markers and with coronary artery disease (CAD). PAF-AH activity and a panel of inflammatory mediators were measured in plasma of 496 patients with CAD and in 477 controls; 276 patients presented with stable angina pectoris and 220 with acute coronary syndrome (ACS). Individuals within the highest quartile of PAF-AH activity had an 1.8-fold increase in CAD risk [95% confidence interval (CI), 1.01 to 3.2; P = 0.…
