• the apoptosis rates for chondrocytes in the growth plate, proliferative zone and resting zone are increased by 1.8-fold and 9.8-fold, respectively, relative to apoptosis rates in wild-type mice
• proliferation of chondrocyte in the proliferative zone is decreased as indicated by a 12% reduction in bromodeoxyuridine-labelled chondrocytes relative to in wild-type mice

• by 9 weeks male mice tibia are 2% shorter than in wild-type mice
• the interterritorial matrix appears to contain less proteoglycan-like amorphous material than in wild-type mice making the collagen fibrils more prominent
• mice exhibit mild pelvic deformation
