The p.Q1702* (in a nonsense allele) and p.E1874K (change) somatic mutations were found in the TET2 gene in tumor-infiltrating leukocytes from patients with primary TNBC [60], and the Q548* (substitution-nonsense) truncating mutation in the TET2 gene was identified in a patient with solid papillary carcinoma with reverse polarity BC [61]. Here, TET2 is linked to breast cancer.
