Two gain regions contained the well-known oncogenes EGFR (7p11.2) and CCND1 (11q13.3) and several known cancer suppressor genes, such as FHIT (3p14.2–p12.1), FAT1 (4q35.1), CDKN2A (9p21.3), and ATM (11q22.3–q24.3), reside within the 10 deletion regions. The gene discussed is ATM; the disease is cancer.
