Mutations in TDP-43 are associated with sporadic and familial cases of Amyotrophic Lateral Sclerosis (ALS), an adult onset, progressive neurodegenerative disease, caused by the selective loss of upper and lower motor neurons in the cerebral cortex, brainstem and spinal cord [9, 10]. The gene discussed is TARDBP; the disease is amyotrophic lateral sclerosis.
