mortality/aging
• mice die within 4 weeks
• mice die within 4 weeks

cardiovascular system
• mice show abnormalities in pectinate muscles in atrial appendages
• cultured attached cardiomyocytes are smaller than similarly treated wild-type cells
• significantly thinner compact myocardium at P1
• at P1, myocardium exhibit widened gaps of intercalated disks with disarrayed sarcomeres and distorted Z lines compared to in wild-type mice
• at P10, membranes of the intercalated disk are highly convoluted and gaps are widened unlike in wild-type mice
• the myocardium exhibits disruption of cell-cell adhesion compared to in wild-type mice
• hearts are abnormally shaped with a bulge at the base of the right ventricle at P20
• hearts are rounder at P1
• mice exhibit disorganized trabeculae that fail to fuse and incorporate into compact myocardium unlike in wild-type mice
• at P20, the ventricular wall exhibits irregular thickness with a thickened right ventricular free wall and thin left ventricular free wall and septum compared to in wild-type mice
• at P20, hearts show fibrosis, esp. in the ventricular septum and within thinned regions of ventricular myocardium
• few cardiomyocytes attack to a plate coated in fibronectin, laminin, and collagen compared with wild-type cells
• progressive, resulting in death

homeostasis/metabolism
• at P20, a large intracardiac thrombus is frequently detected in the left atria
• extensive in the lungs and liver
