mortality/aging

neonatal lethality, complete penetrance ( J:110783 )

• 70% of homozygotes die within 1-2 hours of birth due to cleft palate; remainder die within 10-24 hours of birth from respiratory complications

growth/size/body

cleft palate ( J:110783 )

• 70% of newborns have cleft palate and die within 1-2 hours of birth

abnormal chest morphology ( J:110783 )

• thorax is small and narrow suggesting reduced ribcage size is reason for lung hypoplasia

disproportionate dwarf ( J:110783 )

• newborn mice have smaller bones of the axial, craniofacial and appendicular skeleton

decreased fetal size ( J:110783 )

• at E17.5 and at the newborn stage, conditional null embryos are 5% shorter than controls

craniofacial

cleft palate ( J:110783 )

• 70% of newborns have cleft palate and die within 1-2 hours of birth

skeleton

abnormal long bone hypertrophic chondrocyte zone ( J:110783 )

decreased long bone epiphyseal plate size ( J:110783 )

• growth plates are significantly shortened in mutants

• in newborns, size reduction is more pronounced with disorganized arrangement of columnar chondrocytes and rounding of the chondrocytes rather than the normal flattened morphology

disorganized long bone epiphyseal plate ( J:110783 )

• in newborns, size reduction is more pronounced with disorganized arrangement of columnar chondrocytes and rounding of the chondrocytes rather than the normal flattened morphology

cellular

decreased cell adhesion ( J:110783 )

• in culture, mutant chondrocytes show reduction of adhesion to fibronectin or collagen I by 30% or 32% respectively compared to controls

abnormal cell cycle ( J:110783 )

• number of cyclin-D positive nuclei is reduced by 40% in the growth plates

decreased cell proliferation ( J:110783 )

• chondrocyte proliferation in the growth plate is reduced by 29% in mutants

respiratory system

pulmonary hypoplasia ( J:110783 )

• remaining mutants suffer from lung hypoplasia and die due to breathing problems

digestive/alimentary system

cleft palate ( J:110783 )

• 70% of newborns have cleft palate and die within 1-2 hours of birth
