Supplementary Table 6 lists all genes with CNV amplifications and homozygous deletions, whereas Table 2 lists the most frequently altered of these genes. Homozygous deletion of TP53, a tumor suppressor gene with the highest mutation frequency in this study, was observed in ten patients with TNBC, indicating that 55 (79%) of the 70 patients in our study cohort had either mutated or deleted TP53. Frequent amplification of NDRG1 and deletion of WRN and ATM were validated by qPCR (Supplementary Figure 2). Here, WRN is linked to neoplasm.
