TP53 exon 4 sequences in CTCs isolated from the triple-negative metastatic patients. (A) Patient ID: TRF001321; (B) patient ID: TRF000155. The TP53 mutations and wild- type sequences present in the selected CTCs are shown; the TP53 exon 4 sequences are also shown for the isolated white blood cells (WBC). The TP53 R110 fs*13 mutations (delC in nucleotide 328 or, delG in nucleotide 329) renders a nonfunctional TP53 by creating a premature stop codon at position 122 of the protein (nucleotide 366). The stop codons generated by the TP53 mutation in some CTCs are shown by an encircle TGA sequence. The mutated regions are indicated in the sequences by vertical boxes.
