N normal phenotype
mortality/aging
• mice begin to die at day 9 or 10 and no mice survive past day 16

cardiovascular system
• decreased in thickness
• at day 1, mice have a 1.2 times higher ratio of heart weight to body weight compared with wild-type and the ratio progressively increases to 1.7 and 2.2 times higher at day 7 and 10
• at 10 days, mice have a modest degree of cardiac fibrosis
• reduced fractional shortening occurs
• left ventricular end-diastolic and -systolic dimensions are larger
• at 7 and 10 days, heart rates are slower

growth/size/body
• at day 1, mice have a 1.2 times higher ratio of heart weight to body weight compared with wild-type and the ratio progressively increases to 1.7 and 2.2 times higher at day 7 and 10
• body weight is decreased by 10% in 7- and 10-day mice compared to that of normal mice
• however, body weight is normal at day 1

muscle
• reduced fractional shortening occurs
• left ventricular end-diastolic and -systolic dimensions are larger
