Of these, 8 regions contained previously characterized amplified oncogenes: GATA4, CCND1, CDK6, MDM2, EGFR, MCL1, ERBB3 and MYB; this is the first report of significant and nearly isolated MYB amplification in gastric adenocarcinoma (S1A Fig). The gene discussed is GATA4; the disease is gastric adenocarcinoma.
