Abstract P127: Chromogranin A Pathway: From Pathogenic Molecule to Renal Disease

Introduction: Chromogranin A (CHGA) is released into circulation with catecholamine from secretory granules of chromaffin cells and post-ganglionic sympathetic neurons. Several CHGA gene polymorphisms contributing to traits of autonomic blood pressure control, hypertension and hypertensive nephropathy have been identified. Plasma CHGA is elevated in hypertension and renal failure. This study seeks to understand the role of CHGA in the...
