Cross-cancer alteration analysis for Abl-1, EGFR, Fyn, LCK, Src, ACK1 (TNK2) tyrosine kinases reveal that these genes are frequently altered in cancers, e.g. EGFR and TNK2 are recurrently amplified and mutually exclusive in a majority of the cancer cases (Table 2). The gene discussed is SRC; the disease is cancer.
