Quizplus · Accepted Answer

Knocking out the superoxide dismutase gene in mice has been shown to result in a shortened lifespan, but not necessarily the development of ALS. Studies have found that mice with this gene knocked out exhibit symptoms similar to ALS, such as muscle weakness and paralysis, but not all mice with this mutation develop the disease. Therefore, while ALS is a potential outcome, it is not the only one and a shortened lifespan is more widely observed.
