COLEC12 expression was significantly correlated with immune cell infiltration in 39 cancer types; 38 of these cancer types showed considerable positive correlations, including BC (N=1077, R=0.46, p=3.1e-57), COAD/READ (N=373, R=0.87, p=2.8e-115), LIHC (N=363, R=0.23, p=1.4e-5), OV (N=417, R=0.68, p=5.3e-57), and PAAD (N=177, R= 0.86, p=4.4e-54). Here, COLEC12 is linked to breast cancer.
