Because 2/5 CLL clonal populations within the del(13q)−/− cohort exhibited both aberrantly high p53 protein and Trisomy12+ (Tri12+) (Figure 7D versus Figure 7E) (factors that in later discussion we consider are linked), these two Tri12+ clones were excluded from a reassessment of del(13q) influence on p53 protein (Figure 7H). Here, TP53 is linked to B-cell chronic lymphocytic leukemia.
