• nearly all aspects of the Tg(Col1a1-Runx2)#Pmt phenotype are reversed
• osteocyte numbers in the cortical bone are reduced compared to in wild-type mice but not as severely as in Tg(Col1a1-Runx2)#Pmt mice
• mice exhibit reduced cortical mineral apposition rates compared with wild-type mice
• fracture rate is increased compared to in wild-type mice but not as severely as in Tg(Col1a1-Runx2)#Pmt mice

• the mineralized midpoint of the hyoid bone is decreased in length compared to in wild-type mice
• however, mineralization occurs unlike in Runx2tm1Mjo heterozygotes
• clavicle is smaller than in wild-type mice but not as severely reduced as in Runx2tm1Mjo heterozygotes
• mice exhibit an increase in bone volume compared with wild-type mice
• mice exhibit an increase in bone volume and trabeculae number and a decrease in trabecular space compared with wild-type mice
• mice exhibit an increase in bone mass compared with wild-type mice
• mice exhibit increased bone formation compared to in wild-type mice

• at P25, mice exhibit a defined nonmineralization area between the anterior and posterior fontanelles compared to in wild-type mice that is larger than in Runx2tm1Mjo heterozygotes
• the midportion of the hyoid bone fails to mineralize unlike in wild-type mice
• to a greater extent than in Runx2tm1Mjo heterozygotes
