Phenotypes

  • Left ventricular end-diastolic volume (BSA-indexed)
  • Left ventricular end-systolic volume (BSA-indexed)
  • Left ventricular mass, BSA indexed
  • Left ventricular ejection fraction
  • Left ventricular concentricity (left ventricular mass / left ventricular end diastolic volume)
  • Left ventricular wall thickness (maximal)
  • Left ventricular wall thickness (mean)
  • Left ventricular global radial strain
  • Left ventricular global longitudinal strain

Experiment summary

This study meta-analyzed seven European HCM GWAS datasets (5,900 cases; 68,359 controls) and integrated multi-trait analyses with UK Biobank cardiac MRI data (N=36,083), identifying 70 loci for HCM (50 novel) and 62 loci for left ventricular traits. Prioritization highlighted SVIL as a novel HCM gene (rare truncating variants ≈10× risk), and Mendelian randomization supported a causal role of increased LV contractility in both obstructive and non-obstructive HCM.
