Consistent with the finding that (i) mutant p53 expression is a defining characteristic of basal-like BC, and (ii) aberrant TTK expression is directly correlated with that of mutant p53, we also observed TTK expression to be significantly elevated in mutant p53-expressing basal-like BC patients (Figure 2c; Pam50 filter of METABRIC data set). The gene discussed is TP53; the disease is breast cancer.
