A major international study has just been published, exploring how ATP1A3 variants affect heart function in people with AHC. The multi-center case-control study spanned 12 centers across 10 countries, analyzing 148 individuals with AHC and 74 controls. The key finding: nearly 70% of individuals with the D801N variant had short QT intervals—a condition linked to ventricular arrhythmias and cardiac arrest. To learn more about what what this means for the AHC community, join us at the AHCF Family Meeting in June. Dr. Landstrom will present these groundbreaking findings.
