Dystrophic muscle in Capn3tm1Jsb/Capn3tm1Jsb mice

muscle
abnormal sarcolemma morphology ( J:66862 )
• disruption of sarcolemmal integrity
dystrophic muscle ( J:66862 )
• mutants develop a progressive mild muscular dystrophy
• most severly affects the psoas, soleus, and deltoid muscles
• Background Sensitivity: dystrophic muscle is evident at 2 months of a age in mutants on a 129/Sv background while it becomes evident in mutants on a mixed 129/Sv and C57BL/6 at 6 months of age
• myofibers exhibit an increase in apoptosis

reproductive system
transmission ratio distortion ( J:66862 )
• transmission ratio distortion, preferred transmission of mutant allele
