Abstract
Dysfunction of the ALS2 gene has been linked to one form of juvenile onset autosomal recessive amyotrophic lateral sclerosis (ALS). Previous in vitro studies suggest that over-expression of ALS2 protects cells from mutant Cu/Zn superoxide dismutase (SOD1)-induced cytotoxicity. To test whether ALS2 plays a protective role against mutant SOD1-mediated motor neuron degeneration in vivo, we examined the progression of motor neuron disease in SOD1(G93A) mice on an ALS2 null background. Our data suggest that deficiency in the ALS2 gene does not affect the pathogenesis of SOD1(G93A) mice.
