Highly expressed in B-cell lymphoma and lung cancer. The disease is caused by variants affecting the gene represented in this entry. Microdeletions encompassing the MIR17HG locus can be responsible of FGLDS2. The microRNAs that are encoded in a MIR17HG intron stimulate growth of cultured lung cancer cells. Product of a dubious CDS prediction. The MIR17HG transcript shows predominant nuclear localization and may not be efficiently translated into protein.
