N normal phenotype
cellular
• at E16.5 abnormal mitochondria are seen in myocardial cells
• at E16.5 apoptotic myocardial cells are seen

mortality/aging
• rarely homozygotes are born alive and die shortly after birth
• most homozygotes die before birth starting around E17.5

cardiovascular system
• at E16.5 but not E15.5 fewer myocardial cells with increased intercellular spaces, fewer myofibrils, and no detectable Z bands are seen
• at E16.5 abnormal mitochondria are seen in myocardial cells
• at E16.5 but not E15.5
• at E17.5 the atria are smaller than normal
• the left ventricular septal wall is thicker than normal
• mutant hearts are longitudinally shorter and laterally wider
• the left ventricular wall is thicker than normal and increased expression of markers of adult cardiac hypertrophy are seen
