PCDHA1 and uterine corpus endometrial carcinoma: Conversely, PCDHA1 mutation was associated with good prognosis in uterine corpus endometrial carcinoma, hence high-risk patients with wild-type PCDHA1 had the lowest survival rates while survival was prolonged by ~ 20% in low-risk patients with mutant PCDHA1 (P = 0.003; Fig. 4).
