mortality/aging

lethality throughout fetal growth and development, incomplete penetrance ( J:93021 )

• double homozygous embryos begin to die around E15.5 with only about 12% of double homozygotes surviving to adulthood

cardiovascular system

ventricular septal defect ( J:93021 )

• at E15.5 ventricular septal defects were seen in 77% of double homozygous embryos often associated with hemorrhages

cardiac hypertrophy ( J:93021 )

• 1 month old mutant heart to body weight ratios are increased and markers of cardiac hypertrophy are upregulated

thin ventricular wall ( J:93021 )

• at E15.5 thin ventricular walls were seen in 20% of double homozygous embryos often associated with hemorrhages

hemorrhage ( J:93021 )

• hemorrhages are seen throughout the body of some mutant embryos at E15.5

growth/size/body

cardiac hypertrophy ( J:93021 )

• 1 month old mutant heart to body weight ratios are increased and markers of cardiac hypertrophy are upregulated

postnatal growth retardation ( J:93021 )

muscle

abnormal skeletal muscle fiber type ratio ( J:127416 )

• soleus muscles show an increase in the percentage of slow myofibers
