Eur J Prev CardiolPublished

  • Genome-wide cross-trait analysis and bidirectional Mendelian randomization study
  • Genome-wide association study (GWAS) data
  • linkage disequilibrium score regression
  • Multi-trait analysis of GWAS (MTAG)
  • Bayesian co-localization
  • latent causal variable analysis

Authors' conclusion

Our study suggests strong genetic correlations between OSA and several CVDs.

Study context

Population
GWAS data on obstructive sleep apnoea (OSA) and cardiovascular diseases (CVDs) (coronary artery disease (CAD), heart failure (HF), myocardial infarction (MI), stroke, atrial fibrillation (AF))
Outcome
Genetic correlations and potential causal relationships between OSA and CVDs

Main finding

As reported in the abstract

Shared loci between OSA and CAD (cross-trait MTAG)

15

Shared loci between OSA and MI (cross-trait MTAG)

25

Shared loci between OSA and HF (cross-trait MTAG)

7

Further findings

Latent causal variable analysis

AF causally associated with OSA; HF showed partial causality

Tissue expression of shared genes

Primarily expressed in blood, heart, kidney, liver, muscle and pancreas
