neurodegenerative pathway amyotrophic lateral sclerosis pathway A late onset, mostly sporadic neurodegenerative disease characterized by the loss of motor neurons in the brain stem and spinal cord. Various pathways are thought to be deregulated and contribute to the condition; among them calcium and/or zinc homeostasis, apoptosis, Cdk5 and calcineurin dependent processes, and in the case of the more rare, genetically inherited form of the disease, mutations in the cytosolic Cu, Zn superoxide dismutase (SOD1) and the subsequent changes in the processes that involve SOD1.
