Expression and Mutations of KCNJ5 mRNA in Japanese Patients with Aldosterone-Producing Adenomas

Abstract

We found that: 1) a significant number of patients with APA had somatic mutations of the KCNJ5 gene; 2) KCNJ5 mRNA levels were higher in the APA with KCNJ5 mutations; and 3) the expression of KCNJ5 mRNA was significantly higher in APA than cortisol-producing adenomas and pheochromocytomas.
