N normal phenotype
skeleton
• anomalies likely result from retarded growth of the mandibular condyle, maxillary sutures, and connective tissue of the dental pulp
• the sternum is short, broad, unsegmented
• abnormalities of the sternum appear to result from retarded growth of the ribs which fails to bring the bilateral sternal bands into close association during development
• one more than normal
• results in sharp kinks in the thoracic or lumbar region

limbs/digits/tail
• the tail is tightly coiled at birth but "opens" as the mouse ages leaving the tail bent into various angles
• compared to other areas of the tail, the tail is thickened where angles occur

mortality/aging
• 24 per cent of mutant mice are dead at birth and more die by weaning but a few survive into adulthood

growth/size/body
• anomalies likely result from retarded growth of the mandibular condyle, maxillary sutures, and connective tissue of the dental pulp
• noticeable at birth

reproductive system
• few among the mutants that survive as adults breed

craniofacial
• anomalies likely result from retarded growth of the mandibular condyle, maxillary sutures, and connective tissue of the dental pulp
