Moreover, two out of ten previously identified oncogenic point mutations that did not result in exon skipping events were also PAC detected in our cohort of breast cancer cell lines: MAP2K4 c.551C>G in MDA-MB-134VI and PTEN c.274G>C in CAMA-1; [16], [17] (Fig. 5). Here, MAP2K4 is linked to breast carcinoma.
