mortality/aging
• mice die on average at 20.9 weeks of age, with survival ranging between 12 and 35 weeks

cardiovascular system
• myocyte enlargement without disarray
• prominent left atria
• biventricular cardiac dilation begins at 4 months of age
• massive left ventricular dilation
• extensive interstitial fibrosis
• dilated cardiomyopathy rapidly progresses
• mice develop diminished left ventricle contractility as heart chamber size increases
• the decay in calcium transients is prolonged in myocytes
• myocyte relaxation is delayed
• however, SR calcium-release velocities, time to 90% peak calcium signal and cell shortening velocities are similar to wild-type
• beta-adrenergic stimulation does not normalize the depressed calcium kinetics
• mice show symptoms of terminal heart failure including dyspnea, lethargy, and peripheral cyanosis

behavior/neurological
• mice eventually show symptoms of terminal heart failure including lethargy

homeostasis/metabolism
• mice eventually show symptoms of terminal heart failure including terminal cyanosis

liver/biliary system

muscle
• myocyte enlargement without disarray
• dilated cardiomyopathy rapidly progresses
• mice develop diminished left ventricle contractility as heart chamber size increases

respiratory system
• mice eventually show symptoms of terminal heart failure including dyspnea

growth/size/body

cellular
• extensive interstitial fibrosis
