Distinct Genetic Risk Profile in Aortic Stenosis Compared With Coronary Artery Disease

JAMA CardiolPublished

  • Genome-wide association study
  • adjusted for coronary artery disease (CAD)
  • Mendelian randomization
  • replication in 2 independent cohorts
  • multicentre
  • Data analyzed October 2022 to July 2023

Authors' conclusion

This GWAS adjusted for CAD found a distinct genetic risk profile for AS at the single-marker and polygenic level.

Study context

Population
Participants of European ancestry from EGAS, UK Biobank, Estonian Biobank and FinnGen with information on comorbid CAD
Participants
18,792 vs 434,249
Comparison
Aortic stenosis (AS) vs controls, adjusted for CAD
  • ASn = 18,792
  • Controlsn = 434,249reference
Outcome
Cardiovascular traits associated with AS adjusted for CAD

Main finding

As reported in the abstract

AS risk loci

17

Loci with novel and independently replicated associations (RNF114A, AFAP1, PDGFRA, ADAMTS7, HAO1)

5

Loci associated specifically with AS, not with CAD

11

Genetic correlation between AS and CAD (SE 0.05; P = 1.60 × 10-3)

0.15

Further findings

OutcomeOR (95% CI)P value
Serum phosphate (Mendelian randomization) — AS vs Controls · AS1.20 (1.11–1.31)P = 1.27 × 10-5
Serum phosphate (Mendelian randomization) — CAD vs Controls · CAD0.97 (0.94–1.00)P = 0.04

BP, BMI and cholesterol metabolism (Mendelian randomization)

Substantially lesser associations with AS compared with CAD
