C10orf55 and osteosarcoma: Besides, to explore the potential functions of these CNV-lncRNAs, we calculated the correlation of 34 CNV-lncRNAs with 19,513 protein-coding genes detected in osteosarcoma (significant correlation threshold set to ∣cor | >0.7 and P < 0.05) using the psych package in R. A total of 294 coding genes significantly associated with 10 CNV-lncRNAs (AL023806.1, TMEM78, C3orf36, CCDC140, C8orf86, FAM106A, CABIN1, PSMB1, CAPN15, and C10orf55) were screened (Supplementary Table 4), which were utilized to perform functional enrichment analysis (Supplementary Table 5).
