Among the 151 predicted dual-role genes, 19 were identified with associated copy-number changes, while 12 genes were critical copy-number cancer driver genes, including ADAM6, BCL2, CACNA2D2, CDKN2B, CLEC1A, DIXDC1, FAM129A, GPSM2, IQGAP2, MAP1B, PALM, and TSPAN4. The gene discussed is TSPAN4; the disease is cancer.
