What determines whether HCN channel dysfunction causes cardiac versus neurological phenotypes?

OPEN

The abstract describes HCN channelopathies affecting both cardiac and neuronal systems, but doesn't explain why some mutations cause arrhythmias while others cause epilepsy or neurodegeneration. This tissue-specificity gap is crucial for predicting clinical outcomes and designing targeted therapies. Gap type: unexplained_observation Source paper: Cardiac and neuronal HCN channelopathies.
