There were 6 tumors with coexisting mutations of the same gene (1 with 2 BRAF, 2 with 2 NRAS, 1 with 2 PIK3CA, 1 with 2 KIT, and 1 with 3 KIT mutations), and 26 tumors with coexisting mutations of different genes, including a tumor with 2 NRAS and one PIK3CA mutation. This evidence concerns the gene BRAF and neoplasm.
