mortality/aging
• 34 of 135 die at a mean age of 224 days with a cumulative mortality of 25%
• premature death is sudden with no signs of heart failure

cardiovascular system
• observe degeneration of cardiomyocytes within larger fibrotic areas of the ventricles at 22 months of age
• develop progressive cardiac fibrosis with age
• although at young ages exhibit enhanced left ventricle contractility, mutants show a loss in hypercontractility as they age (J:108867)
• exhibit an increase in left ventricular (LV) dP/dt max and the ratio of dP/dt max to dP/dt min (J:108879)
