There were also no significant differences in age at adrenalectomy or tumor size between patients that harbored a KCNJ5 mutant APA, compared to patients that harbored a KCNJ5 wild-type APA (47 ± 12.6 vs. 46 ± 11.0 years old; 13.6 ± 4.47 vs. 13.0 ± 4.39 mm), though male patients in general tended to have adrenalectomy at an older age than females (49 ± 12.0 vs. 43 ± 10.2, p = 0.056; Table 2). Here, KCNJ5 is linked to neoplasm.
