mortality/aging
• mice die immediately after birth

respiratory system
• mice make feeble attempts to breathe

homeostasis/metabolism
• skin remains bluish-grey until death

skeleton
• long bones are shorter, thicker, and deformed with mildy splayed ends
• irregular metaphyseal margins in the long bones
• the thoracic cage is narrow and bell-shaped
• smaller in height and exhibit advanced ossification involving both the vertebral bodies and the articular processes
• bony trabeculae of the primary spongiosa are shortened and distorted
• zone of resting chondrocytes and the zones of proliferation and maturation are shortened, however the numbers of multinucleated chondroclasts and osteoclasts are normal
• columns of proliferating chondrocytes are shorter and irregularly arranged
• cartilage primorida of the ulna and radious are deformed and shortened at E14.5 but not at E12.5
• exhibit osteochondrodysplasia
• excessive/advanced mineralization
• exhibit acceleration of the normal endochondral ossification process and also abnormal maturation of hyaline rib chondrocytes with associated perichondral ossification
