LCK and neoplasm: Both chromosomes harbor many potential tumor suppressors, including regulators of cell death, such as Tm2d1, Utp11l, Trp73, Dffa, Runx3, Lck, Dhcr24, Faf1, Pax7, and Casp9, and effectors of cell death, such as Col18a1, Gadd45b, Dapk3, and Casp14. Among all the tumors assayed (n = 18), we identified nearly five-hundred loci (Table S9 in File S1) with potential copy number gains.
