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
• partial ossification of the scapula and ileum
• however, some ossification of zeugopod elements and other skeletal elements is observed
