Official Title: Metabolism of Patients With Genetically Caused Cardiac Arrhythmia
Brief Summary: Loss-of-function mutations in voltage-gated potassium channels cause long QT syndrome (LQTS) due to a prolonged cardiac repolarisation phase. Hypoteses: patients with loss-of-function mutations also exhibit altered hormone release upon glucose ingestion.
Detailed Summary:
Loss-of-function mutations in voltage-gated potassium channels cause long QT syndrome (LQTS) due to a prolonged cardiac repolarisation phase.
Voltage-gated potassium (Kv-) channels are known for their relation to malignant cardiac arrhythmias, but also play a role in pancreatic alpha- and beta cell hormone secretion, and possibly in incretin hormone secretion. We hypothesised that patients with loss-of-function mutations also exhibit altered hormone release upon glucose ingestion.
