The breast cancer-related phenotype (MIM:114480), 11 known genes (BRCA2, PALB2, NBN, PIK3CA, RAD51, AKT1, CHEK2, XRCC3, BRCA1, BRIP1, FAM175A) and 11 known lncRNAs (BCYRN1, CDKN2B-AS1, GAS5, H19, HOTAIR, MIR31HG, MALAT1, MEG3, PVT1, UCA1, XIST) were used as seeds, and LncPriCNet, RWRHLD and RlncD were applied to score 528 differential lncRNAs. The gene discussed is BCYRN1; the disease is breast cancer.
