Key:
phenotype observed in females WTSI Wellcome Trust Sanger Institute
phenotype observed in males EuPh Europhenome
N normal phenotype
       
growth/size
• lower body weight than their littermate control
• short-limbed dwarfism
• shorter endochondral bones than their wild type littermates at 11 week of age
• skull was unaffected
• no overt skeletal phenotype at birth

limbs/digits/tail
• femurs are 21% shorter than wild type from 1 week to 10 weeks of age
• the differences maintained at 1 year of age
• no overt skeletal phenotype at birth

skeleton
• fewer osteoclasts localize to the vascular invasion front of the growth plate
• femurs are 21% shorter than wild type from 1 week to 10 weeks of age
• the differences maintained at 1 year of age
• no overt skeletal phenotype at birth
• expanded hypertrophic zones of the growth plates in tibia, femur and ribs
• expansion of the hypertrophic zone is apparent at birth and still apparent at 7 weeks of age
• nomal pattern of trabecular bone deposition beneath the expanded growth plates
• normal chondrocyte proliferation rates
• distorted pelvis shape
• pelvis length is significantly shorter compared to wild type from 1 week of age

cellular
• the secretion of mutant protein is reduced and significantly delayed in the hypertrophic zone
• intracellular retention of the mutant protein apparent in the upper hypertrophic zone
• increased endoplasmic reticulum stress in hypertrophic chondrocytes
• induced unfolded protein response

hematopoietic system
• fewer osteoclasts localize to the vascular invasion front of the growth plate

immune system
• fewer osteoclasts localize to the vascular invasion front of the growth plate
