ARID1A and hepatocellular carcinoma: Furthermore, analysis of WES data from HCC samples in the Cancer Genome Atlas Program (TCGA), the International Cancer Genome Consortium (ICGC), cBioPortal, NODE database, and published reports[25, 26, 27, 28, 29, 30, 31, 32, 33] revealed that 212 HCC patients with non‐synonymous ARID1A mutations showed a 0.824 cosine similarity with SBS B, characterized by C>T substitutions (31.0%) (Figure 2F).
