MGI Phenotype PHENOTYPE: Homozygotes for targeted null mutations exhibit cell loss and peri-implantation lethality. Muscle-specific KO mice show muscle necrosis leading to paralysis and death. Neuron-specific KO mice show muscle degeneration associated with loss of motor axons. [provided by MGI curators]
