cellular
• osteoblast proliferation is increased compared to in wild-type mice

craniofacial
• although normal at birth, mice develop craniofacial abnormalities beginning at P3
• mice exhibit facial asymmetry with anterio-posterior shortening, lateral widening and vertical heightening compared with wild-type mice
• mice exhibit midface hypoplasia compared with wild-type mice

skeleton
• osteoblast proliferation is increased compared to in wild-type mice
• although normal at birth, mice develop craniofacial abnormalities beginning at P3
• due to increased osteoblast proliferation
• at P16 to P21, mice exhibit premature fusion of the frontal, saggital, and coronal sutures unlike in wild-type mice
• lamboid and occipitointerparietal sutures appear normal
• no cranial base abnormality is observed at P20
• at P16 to P21, mice exhibit premature fusion of the coronal sutures unlike in wild-type mice
• at P16 to P21, mice exhibit premature fusion of the anterior frontal and posterior frontal sutures unlike in wild-type mice
