Abstract Increased late sodium current (INaL) is a central mechanism underlying both inherited and acquired cardiac arrhythmias. Although Nav1.5 is the dominant cardiac sodium channel, multiple tetrodotoxin-sensitive (TTX-S) Nav isoforms are also expressed in cardiomyocytes, particularly within transverse tubules, wher...

This study highlights the effectiveness of hiPSC-CMs and EHTs in recapitulating the clinical phenotype of desminopathy, providing a platform for investigating the mechanisms of early-onset cardiac arrhythmias and SCD.

The findings support a model in which non-SCN5A BrS is associated with early dysregulation of developmental transcriptional networks controlling cardiac conduction and extracellular matrix organization, whereas SCN5A-mediated BrS primarily results from sodium channel deficiency with limited developmental remodeling.
