Correlations in variant densities among samples from Caucasian populations. Heatmap of Pearson’s correlations of per-gene variant densities between pairs of samples from Caucasian populations. The 1522 samples are sorted by their cancer types. The correlation values show high similarity among cancer types sequenced by the same canter. The cancer types are as reported in Fig. 1. BRCA (Breast Invasive Carcinoma, 291 samples), UCEC (Uterine Corpus Endometrial Carcinoma, 169 samples), STAD (Stomach Adenocarcinoma, 248 samples), SKCM (Skin Cutaneous Melanoma, 435 samples), LIHC (Liver Hepatocellular Carcinoma, 146 samples) and THCA (Thyroid Carcinoma, 258 samples). Color for the sequencing centers are as in Fig. 1
