involves: 129S1/Sv * 129X1/SvJ * C57BL/10ScSn
Key:
phenotype observed in females
phenotype observed in males
N normal phenotype
mortality/aging
• 3 of 11 die before weaning
• lifespan is 3-11 weeks

growth/size/body
• exhibit poor growth

muscle
• develop a moderate to severe cardiomyopathy similar to that of double mutant Utrntm1Jrs and Dmdmdx mice
• develop severe skeletal dystrophy, however muscles are no more dystrophic than muscles of double Utrntm1Jrs and Dmdmdx mutant mice

cardiovascular system
• develop a moderate to severe cardiomyopathy similar to that of double mutant Utrntm1Jrs and Dmdmdx mice

skeleton

limbs/digits/tail
• severe limb contractures

nervous system
• distribution of acetylcholine receptors within synapse branches is abnormal, with a patchy or granular distribution
