Several lncRNAs, such as ARNILA, LINK‐A, and MALAT1, have been found dysregulated in TNBC and are considered as new therapeutic targets.5, 6, 7 LncRNA human histocompatibility leukocyte antigen (HLA), HLA complex P5 (HCP5), is primarily found expressed in immune system cells and had a potential role in autoimmunity.8 Recent studies reported that HCP5 showed aberrant expression in some human cancers. This evidence concerns the gene HCP5 and Autoimmunity.
