mortality/aging
• the condition of mutants begins to deteriorate around 8 weeks of age and the average life span is only 10 - 18 weeks

behavior/neurological
• mutants are unable to support their own weight in the hanging wire grip test
• walking track analysis indicates that mutants have an abnormal gait
• mutants have a shorter stride length

cardiovascular system
• the distinct organization of contractile filaments is significantly reduced in mutants
• at 6 weeks of age the heart is smaller than normal

endocrine/exocrine glands
