growth/size/body
• severe dwarfism

skeleton
• reduced width of skull
• osteoclasts per bone area are increased
• osteoclast surface area/bone surface area is increased
• fewer subchondral trabeculae
• trabeculae only partially mineralized
• more abundant collagen deposition
• significantly lower bone volume/trabecular volume in distal metaphysis of the femur
• smaller hypertrophic mineralization zone
• reduced size of epiphysis
• defect in mineralization of calcified cartilage and primary spongiosa

craniofacial
• reduced width of skull

hematopoietic system
• osteoclasts per bone area are increased
• osteoclast surface area/bone surface area is increased

immune system
• osteoclasts per bone area are increased
• osteoclast surface area/bone surface area is increased
