phenotype observed in females

N normal phenotype
behavior/neurological
• slower to learn task in a Morris Maze test
• travelled further to find the hidden platform
• little retention of learning seen during probe trials in a Morris Maze test
• less time spent in the periphery of an open field test
• perform poorly on a rotarod
• fall of a rotarod more rapidly and at slower speeds
• rotarod performance does not improve with practice
• 25% more errors than controls on a notched bar test of hindlimb performance
• investigation of a newly introduced mouse is normal
• no distinction made between mice after the later introduction of a second new mouse

cardiovascular system
• seen in mice with a full atrioventricular canal defect
• in one mouse that also displayed a ventricular septum defect
• some mice exhibit hearts that are tilted onto their right unlike in wild-type mice
• one mouse exhibited an atrioventricular septal defect associated with unfused atrioventricular cushions
• 7 of 11 mice exhibit a perimembranous ventral septal defect such that the ventricular septum fails to fuse to the proximal outflow cushion tracts

nervous system
• mice exhibit a reduction in the number of granule neurons in the cerebellum compared to wild-type mice

behavior/neurological
• mice spend less time exploring a novel object than wild-type mice

craniofacial
• mutant mice exhibit a mandible that is smaller between the coronoid process and the mandibular angle and between the coronoid process and the most superior point of the incisor alveolar rim

skeleton
• mutant mice exhibit a mandible that is smaller between the coronoid process and the mandibular angle and between the coronoid process and the most superior point of the incisor alveolar rim
