mortality/aging
• incomplete penetrance; postulated to be due to intraabdominal bleeding caused by birth trauma (J:44598)

behavior/neurological
• mice exhibit an ataxic gait described as tottering and wobbling
• obvious by 3 weeks of age; animals exhibit jerky movements with balance defects and occasional falls; mice will fall off a rotarod immediately while controls stayed on

hematopoietic system
• platelets from homozygous mice failed to aggregate or release ATP upon activation; however, cell shape changes consistent with activation were noted (J:42882)
• intracellular calcium was not mobilized and InsP3 was not formed upon platelet stimulation (J:42882)
• blood platelet counts were similar to controls (J:42882)
• in high shear stress experiments, platelets form small aggregates that are no more than 2 cell layers thick and total platelet deposition is 70% less than in wild-type mice (J:118488)
• however, platelet calcium response is normal (J:118488)

nervous system
N
• no overt defects in brain architecture was detected; synaptic transmission was similar to controls in stimulus intensity and PPF tests (J:44598)
• hippocampus is indistinguishable from wild-type in overall structure and gross morphology (J:126972)
• beta-adrenergic modulation of sIAHP is normal in hippocampus of mutants (J:126972)
• defect in regression of supernumerary climbing fibers; Purkinje cells are multiply innervated by climbing fibers and remain so after postnatal week 3
• in hippocampus, apamin-sensitive IAHP in absence of neuromodulatory agents are intrinsically smaller than in wild-type
• effects of metabotropic glutamate receptor agonists carbachol and DHPG on sIAHP are strongly reduced
• exhibited in homozygous mice when either induced by agonist or by paired-pulse low frequency stimulation

homeostasis/metabolism
• platelets from homozygous mice failed to aggregate or release ATP upon activation; however, cell shape changes consistent with activation were noted (J:42882)
• intracellular calcium was not mobilized and InsP3 was not formed upon platelet stimulation (J:42882)
• blood platelet counts were similar to controls (J:42882)
• in high shear stress experiments, platelets form small aggregates that are no more than 2 cell layers thick and total platelet deposition is 70% less than in wild-type mice (J:118488)
• however, platelet calcium response is normal (J:118488)
• in a tail tip amputation test, homozygous mice continued to bleed from the wound for 30 minutes or more; controls stopped bleeding in 4-8 minutes
