phenotype observed in females
phenotype observed in males
N normal phenotype
mortality/aging
• mice died between 6 weeks and 6 months of age

behavior/neurological
• mice exhibited greater kaniate-induced seizure susceptibility than controls
• animals exhibited a limb clasping reflex when lifted by the legs; control mice extended their legs

growth/size/body
• growth defects were noted by 2 weeks of age; most mice did not increase in size after 5 weeks of age

reproductive system
• 70% of homozygous male mice exhibited priapism
• males failed to produce litters despite the presence of sperm in the seminiferous tubules

nervous system
• mice exhibited greater kaniate-induced seizure susceptibility than controls
• a progressive reduction in the number of pyramidal cells was seen in the CA3 region of the hippocampus
• seen in the CA3 region of the hippocampus
