mortality/aging
• mice die shortly after birth

skeleton
• all skeletal elements are shortened
• mice exhibit partial bone collar
• mice exhibit extra cartilage elements (typically 4) in the zeugopod and in some autopods
• at the diaphysis
• profound defect in ossification of the craniofacial, the rest of the axial, and the appendicular skeleton
