Motor neuron diseases (MNDs) are neurodegenerative disorders that lead to paralysis and typically carry a dismal prognosis. In children, inherited spinal muscular atrophies are the predominant diseases that affect motor neurons, whereas in adults, amyotrophic lateral sclerosis, which is inherited but mostly sporadic, is the most common MND. In recent years, we have witnessed a revolution in this field, sparked by the discovery of the genes that cause MNDs. Remarkably, at least 10 genes, whose products are either RNA-binding proteins or proteins that function in RNA processing and regulation, cause MNDs and place the dysregulation of RNA pathways at the center of motor neuron degeneration pathogenesis.
