nervous system
abnormal trigeminal nerve morphology ( J:109043 )
• at E11.5, the ophthalmic branch of the developing trigeminal nerve is absent; however, no trochlear nerve abnormalities are detected and diaphragm innervation is similar to wild-type at E18.5

endocrine/exocrine glands
abnormal mammary gland development ( J:109023 )
• terminal end buds of mammary gland explants are abnormal similar to NtnGt(pGT1.8TM)629Wcs homozygous explants
• terminal end buds are also disorganized
• an 8-fold increase in apoptosis is seen in detached cap cells
• growth of explants is slower compared to wild-type
