PCDH1 and breast cancer: Of the 97 nDNA-encoded phage sequences significantly associated with the diagnosis of invasive BC by autoantigen microarray analyses, several clones mapped to the Long Intergenic Non-Protein Coding RNA 2381 (LINC02381), and to intergenic phages that may be parts of uncharacterized lncRNAs adjacent to the ERCC Excision Repair 4 (ERCC4), C-X-C Motif Chemokine Ligand 13 (CXCL13), SRY-Box Transcription Factor 3 (SOX3), Protocadherin 1 (PCDH1), Epididymal Protein 3B (EDDM3B), and Growth Factor Receptor Bound Protein 2 (GRB2) genes (Figures 6, 7; Table 2; Supplementary Table S2).
