Furthermore, among 10 845 TCGA tumor samples, CHD7 had high‐level amplification in 362 cases (0.9%), in which five tumor types, namely breast, ovarian, uterine, and liver cancers and melanoma, exhibited CHD7 amplification in more than 5% of cases (Fig. 1A and Table S2). The gene discussed is CHD7; the disease is neoplasm.
