Several lncRNAs are dysregulated in AD (Sox2OT, 1810014B01Rik, BC200, BACE1-AS, NAT-Rad18, 17A, GDNFOS), Parkinson’s disease (naPINK1, Sox2OT, 1810014B01Rik, BC200), and Huntington’s disease (highly accelerated region 1A (HAR1F), HTTAS, DiGeorge syndrome critical region gene 5 (DGCR5), nuclear paraspeckle assembly transcript 1 (NEAT1), taurine up-regulated 1(TUG1)) [26]. The gene discussed is DGCR5; the disease is Alzheimer disease.
