Additionally, the surgically primary tumor specimen and the metastatic tumor specimen were sequenced, and it was discovered that mutations of c-KIT c.1668_1679delGTGGAAGGTTGT in exon 11 and c.1926delA in exon 13 were present in both the surgically primary and metastatic tumors (Figures 2B,C, respectively). The gene discussed is KIT; the disease is neoplasm.
