Placenta defect and small liver size in Gab1^tm3Wbm/Gab1^tm3Wbm, Gab1^tm2Wbm/Gab1^tm2Wbm and Gab1^tm2WbmGab1^tm3Wbm mice

mortality/aging

lethality throughout fetal growth and development, complete penetrance ( J:125303 )

• mice live up to E16 but are never born

embryo

thin placenta labyrinth ( J:125303 )

• at E14.5, the labyrinth layer is half the thickness of wild-type labyrinth layers

disorganized placental labyrinth ( J:125303 )

• mice develop a disorganized labyrinth layer

liver/biliary system

decreased liver weight ( J:125303 )

• at E14.5, the liver to body weight ratio is 5.5% compared to 8% in wild-type mice

craniofacial

palatal shelves fail to meet at midline ( J:125303 )

cleft secondary palate ( J:125303 )

• at E16, the secondary palate remains open in one third of mice

muscle

muscle phenotype ( J:125303 )

N	• unlike mice with other altered Gab1 alleles, emigration of muscle progenitors is comparable to in wild-type mice and limbs form normally

digestive/alimentary system

palatal shelves fail to meet at midline ( J:125303 )

cleft secondary palate ( J:125303 )

• at E16, the secondary palate remains open in one third of mice

growth/size/body

palatal shelves fail to meet at midline ( J:125303 )

cleft secondary palate ( J:125303 )

• at E16, the secondary palate remains open in one third of mice
