The long non-coding WDFY3-AS2 RNA was identified as downregulated in breast tumors relative to normal tissue (Fig 4A), and according to previous analyses in this study, low expression of this transcript was associated with worse prognosis in women with breast cancer (Fig 5A and 5B; Table 1; S1 and S2 Tables). Here, WDFY3 is linked to breast carcinoma.
