Abstract 18116: Genetic Associations With Atherosclerotic Abdominal Aortic Calcification (original) (raw)

Circulation, 2015

Abstract

Background: There is limited information regarding genetic contributions to atherosclerotic aortic calcification, an important predictor of cardiovascular disease. Methods: We conducted a genome-wide association study (GWAS) meta-analysis with subsequent replication analysis to define single nucleotide polymorphisms (SNPs) associated with abdominal (AAC) or thoracic aortic calcification (TAC). AAC and TAC were quantified using multi-detector computed tomography. SNPs were assayed by Illumina or Affymetrix arrays and imputation at the cohort level was performed using data from the 1000 Genomes project. Results: 9417 individuals of European descent from four cohorts of the Cohorts for Heart and Aging Research in Genome Epidemiology (CHARGE) consortium were included in the AAC discovery analysis and 8422 individuals from five cohorts in the TAC discovery analysis. SNPs achieving genome-wide significance were tested for replication in four additional cohorts with Hispanic-American (HA) ...
