Similarly, the lncRNA LINC00461 and its mouse homologue NDIME, which were found to be associated with autism and ADHD [35,55], regulate the expression of the MEF2C gene, which encodes a transcription factor, the myocyte-specific enhancer factor 2C [35,93]. The gene discussed is MIR9-2HG; the disease is attention deficit-hyperactivity disorder.
