Although increases in left ventricular mass index (LVMI) and left ventricular hypertrophy (LVH) has been detected in KCNJ5-mutant carriers [21, 22], evidence evaluating the outcome of vascular status in those with KCNJ5 somatic mutations after adrenalectomy was insufficient. Here, KCNJ5 is linked to left ventricular hypertrophy.
