This method showed that BST2 expression was significantly involved in the CM patients’ prognosis (cutoff value = 8.572, P < .001, Chi-square = 22.172), GBP5 (cutoff value = 2.991, P < .001, Chi-square = 32.597), and AIM2 (cutoff value = 3.103, P = .002, Chi-square = 9.741) (Fig. 6E–G). This evidence concerns the gene BST2 and cutaneous mastocytosis.
