Studies have found that patients with melanoma can be divided into high-risk groups and low-risk groups with different survival times by a molecular signature of six lncRNAs, including LINC01260, HCP5, PIGBOS1, RP11-247L20.4, CTA-292E10.6, and CTB-113P19.5 [22]. This evidence concerns the gene HCP5 and melanoma.
