N normal phenotype
mortality/aging
• mice display higher mortality, with no mice surviving past 20 weeks

cardiovascular system
• cardiomyocytes are enlarged and cardiomyocyte nuclei are enlarged
• mice develop enlarged hearts
• however, hearts are normal at 4-8 weeks of age
• cardiomyocytes are enlarged and expression of hypertrophic marker genes are elevated
• ventricular walls are only moderately thicker at 10 weeks of age
• dilated hearts show mild fibrosis
• mice develop dilated cardiomyopathy
• fractional shortening is reduced, indicating contractile dysfunction
• echocardiography at 8 weeks of age indicates increased systolic dimensions and a tendency towards increased diastolic diameters of the left-ventricular chamber
• ECG-analysis indicates atrial fibrillation in 5 of 8 mice
• mice frequently exhibit premature ventricular beats
• in a severe case, spontaneous pauses in contraction lasting longer than 5 seconds are seen, most likely due to sinoatrial block
• mice exhibit symptoms indicative of congestive heart failure

homeostasis/metabolism
• atria frequently contain organized thrombi
• severe anasarca in severe cases

muscle
• cardiomyocytes are enlarged and cardiomyocyte nuclei are enlarged
• mice develop dilated cardiomyopathy
• fractional shortening is reduced, indicating contractile dysfunction

growth/size/body
• mice develop enlarged hearts
• however, hearts are normal at 4-8 weeks of age
• cardiomyocytes are enlarged and expression of hypertrophic marker genes are elevated
