cardiovascular system
• irregular and reduced vascular network associated with the nasal bones, the mucosa underlying the nasal bones, and the vomeronasal organ

craniofacial
• lack of growth within the frontonasal sutures, putatively due to premature osteoblast differentiation
• diminished interdigitation of the frononasal sutures, whereas that of the premaxillary sutures is similar to wild-type
• increased incidence of ectopic interfrontal which was observed in only 44% of all other mice, but in 100% of these conditional homozygotes
• ~13% shorter than those of wild-type
• anterior shift of upper incisors as a result of altered arrangement of facial bones
• defects become evident between P10 and P21, increase with age, and are more severe at the distal end
• unlike wild-type, the nasal bones are ""concave"" from a lateral view and tend to be squared off
• increased mineralized portion relative to wild-type, putatively due to premature osteoblast differentiation and consequent inappropriate secretion of mineralized matrix that perturbs postnatal suture growth
• abnormal and shortened by ~18% relative to those of wild-type
• septal regions containing immature, rather than mature proliferating, chondrocytes
• due to impaired growth at the frontonasal suture

limbs/digits/tail
N
• no defects were observed in either the forelimbs or hindlimbs

respiratory system
• defects become evident between P10 and P21, increase with age, and are more severe at the distal end
