CDKN2C and lymphoma: After monitoring a cohort of 29 p18−/−;Gata3+/−, 17 p18−/−, 8 Gata3+/− or p18+/−;Gata3+/− and 12 WT or p18+/− mice for 8–22 months, we found that 46% (n = 11) and 50% (n = 18) of p18−/−;Gata3+/− mice developed spontaneous lymphomas at 8–14 and 14–22 months of age, respectively, whereas no WT, Gata3+/− or p18−/− mice formed lymphomas at similar ages (Figure 4 and Table 1).
