N normal phenotype
mortality/aging
• incomplete penetrance
• whereas approximately one-third of males appeared healthy, others showed growth retardation, weakness, craniofacial defecfs, and died prior to weaning

craniofacial
• incomplete penetrance

endocrine/exocrine glands
• varying degrees of penetrance observed
• all three pituitary lobes are present at birth
• varying degrees of penetrance observed
• altered development leading to the defects including disorganization and abnormalities of Rathke's pouch
• bifurcation of Rathke's pouch and the presence of extra Rathke's pouch clefts and linings
• increased necrosis and empty tubules in the most severely affected mice

growth/size/body
• incomplete penetrance
• some males showed decreased growth and general weaknesss, these mice did not survive to weaning

reproductive system
• increased necrosis and empty tubules in the most severely affected mice

nervous system
• dysgenesis observed in the most severely affected mice
• failure of the dorsal hippocampal commissure to cross the midline in the most severely affected mice
• the floor plate was expanded relative to that of wild-type
• varying degrees of penetrance observed
• all three pituitary lobes are present at birth
• varying degrees of penetrance observed
• altered development leading to the defects including disorganization and abnormalities of Rathke's pouch
• bifurcation of Rathke's pouch and the presence of extra Rathke's pouch clefts and linings
• abnormal continuity of the intercerebral fissure with the third ventricle in the most severely affected mice
• the presumptive hypothalamus appeared thinner and shorter than that of wild-type embryos

homeostasis/metabolism
• in the pituitary
