In this study, we identified that BRCA1, a tumour suppressor gene responsible for DNA double‐strand break‐repair, is the cellular target of BART2‐5p, BART12, BART17‐5p and BART19‐3p, in which BART17‐5p and BART19‐3p constitute ~8.6% of the total viral miRNAs in NPC.13 Here, BRCA1 is linked to neoplasm.
