Complicated: The smn2 gene provides instructions for making the survival motor neuron (smn) protein. The smn protein is found throughout the body, with high levels in the spinal cord. This protein is particularly important for the maintenance of specialized nerve cells called motor neurons, which are located in the spinal cord and the part of the brain that is connected to the spinal cord (the brainstem).
