N normal phenotype
skeleton
• abnormal and shortened limb skeletal elements are visible by E13.5
• absent middle phalange on digit V
• severely shortened middle phalanges on digits II - IV
• decrease in the number of proliferating cells in the developing cartilage anlagen of the long bones at E15.5
• expression analysis indicates a delay in endochondral bone ossification at E14.5

limbs/digits/tail
• absent middle phalange on digit V
• severely shortened middle phalanges on digits II - IV
• marked decrease in the length of the most distal cartilage element before the last joint formation
• decrease in the recruitment of surrounding proliferating mesenchymal cells into the most distal cartilage element
