the catecholamine release–inhibitory fragment catestatin. We identified a natural
nonsynonymous variant of catestatin, Gly364Ser, that alters human autonomic function and
blood pressure. Methods and Results—Gly364Ser heterozygotes and controls underwent
physiological and biochemical phenotyping, including catecholamine production,
chromogranin A precursor, and its catestatin product. Case-control studies replicated effects …
