A set of 48 dysregulated miRNAs targeting the critical genes other than the parent genes (BRD4 and NUT) was identified.Functional enrichment analysis of KEGG pathways of target genes of these Ex-miRNAs implicates their role in cancer pathways.Amplification in the expression level of these miRNAs can be used for NMC diagnosis and prognosis. The gene discussed is BRD4; the disease is nut midline carcinoma.
