In the TCGA cohort of patients with breast cancer, cGAS-STING scores were not related to different clinical subgroups (tumor size, P = 0.075, Supplementary Fig. 3b; clinical stage, P = 0.23, Supplementary Fig. 3c; lymph node states, P = 0.684, Supplementary Fig. 3d). Here, CGAS is linked to breast cancer.
