N normal phenotype
craniofacial
• broad face (J:63816)
• the anteroposterior axis was significantly shortened, whereas the dorsoventral and medial-lateral axes were enlarged (J:209611)

vision/eye
• wide-spaced eyes

growth/size/body
• broad face (J:63816)
• the anteroposterior axis was significantly shortened, whereas the dorsoventral and medial-lateral axes were enlarged (J:209611)

nervous system
• gray matter and total brain volumes were significantly larger in Bfc/+ (P < 0.05; 1-way ANOVA)
• the corpus callosum appeared to be severely underdeveloped in 3 Bfc/+ individuals, and lacked any inter-hemispheric extensions
• globus pallidus is slightly, but significantly, larger in Bfc/+
• striatum is slightly, but significantly, larger in Bfc/+
• thalamus is slightly, but significantly, larger in Bfc/+
• the length and number of neurites were significantly increased after only 1 day in culture
• after 8 days in culture, the extent of dendritic branching in heterozygous neurons was dramatically lower than in controls
• mutants showed substantially reduced cerebellar and olfactory bulb volumes compared with controls
• mutants showed substantially reduced cerebellar and olfactory bulb volumes compared with controls
• heterozygotes, a lower density of docked synaptic vesicles (SV) in cortex and in hippocampus CA1 region is seen
• long-term potentiation (LTP) induced by either tetanic or theta-burst stimulation was significantly reduced in hippocampus CA1 slices from heterozygous mice
• heterozygous mice mice show significant PPI deficits but acoustic startle response is comparable to controls

behavior/neurological
• freezing behavior in heterozygous mice using a standard fear conditioning protocol for contextual memory is significantly lower than that of littermate controls, suggesting that mutants have a reduced capacity to recall the previous shock exposure
• for trials in which rewards are given after a light event, responses increase significantly during the expected time interval in control mice, but not in heterozygous mutants
• in probe trials where no reward is given, responses of heterozygous mutant mice during the critical time window is significantly lower than littermate controls
• control animals improve performance with repeated trials in the hidden platform variation of the water maze test, but heterozygous mutant mice did not improve
• heterozygous mice show a significantly shorter latency period before falling from the rod in a challenging rotarod test incorporaing 6 consecutive accelerating stages in a single session; no differences are seen in a standard rotarod test
• heterozygous pups exhibit a significant reduction in the total number of vocalizations with more of these calls characterized by a single component compared to controls
