ALS caused by mutations of this gene affect diverse ethnicities. The average age of onset is age 43 with a survival time of about 33-41 months. ALS resulting from this gene mutation is most commonly cervical with severe lower motor neuron loss in the spinal cord and less in the brainstem. RNA metabolism is also affected. This mutation accounts for about 3-5% of familial ALS cases.
Because records on ALS have not been kept throughout the country, it is hard to estimate the number of ALS cases in the United States. ALS is slightly more common in men than women. ALS is age related; most people find out they have it when they are between 55 and 75 years of age, and live from 2 to 5 years after symptoms develop. How long a person lives with ALS seems to be related to age; people who are younger when the illness starts live slightly longer.
