Thoracic aortic disease: prognostic role of gene variants and polygenic risk scores

Eur Heart JPublished

  • Genetic association study
  • two biobank cohorts

Authors' conclusion

P/LP HTAAD gene variants confer a substantial population-level increased risk of TAAD. Polygenic risk represents an additive factor for rare variant TAAD risk

Study context

Population
Participants of Penn Medicine Biobank (PMBB) and MyCode Biobanktwo biobank cohorts
Comparison
P/LP heritable TAAD (HTAAD) gene variant carriers vs non-carriers; polygenic risk score
Outcome
TAAD, identified by algorithmic review of electronic health records
