Abstract excerpt
RATIONALE: Congenital central hypoventilation syndrome (CCHS) is caused by PHOX2B gene variants, resulting in highly variable cardiac autonomic dysregulation, including abrupt sinus pauses and risk of sudden unexpected death. The relationship between age, PHOX2B genotype, and cardiac autonomic dysfunction remains unknown, and CCHS-related physiomarkers are lacking. OBJECTIVE: To assess the impact of age and...
