♀ phenotype observed in females
♂ phenotype observed in males
N normal phenotype
mortality/aging
postnatal lethality, incomplete penetrance ( J:195050 )
• under represented by 75% at weaning but found at the expected frequency at E18.5

cardiovascular system
increased heart weight ( J:195050 )
• cardiomegaly occurs postnatally as heart to body mass ratio is similar to controls at E18.5
abnormal semilunar valve morphology ( J:195050 )
• enlarged at E18.5
• valve cusps appear hyperplastic with a 43% increase in the median number of cells and 57% increase in thickness
• increase in thickness is persistent in adults
• however, unlike in global null mice atrioventricular valve leaflets are not overtly abnormal
abnormal aortic valve cusp morphology ( J:195050 )
• the glycosaminoglycan/proteoglycan-rich spongiosa layer of the extracellular matrix is enlarged with increased space between the granules
• 9 of 13 mutants have at least one cusp with aberrant localization and/or excessive levels of collagen
aortic valve stenosis ( J:195050 )
• in surviving adults
increased heart left ventricle size ( J:195050 )
• increase in left ventricular end diastolic dimension in females at 24 to 28 weeks of age
increased heart left ventricle weight ( J:195050 )
• increase in heart size is primarily due to expansion of the left ventricle
decreased cardiac muscle contractility ( J:195050 )
• decrease in ejection fraction ad fractional shortening in males and females at 24 to 28 weeks of age
abnormal aortic valve flow ( J:195050 )
• increase in aortic valve peak velocity in females at 24 to 28 weeks of age
increased heart rate ( J:195050 )
• at 24 to 28 weeks of age in females

muscle
decreased cardiac muscle contractility ( J:195050 )
• decrease in ejection fraction ad fractional shortening in males and females at 24 to 28 weeks of age

growth/size/body
increased heart weight ( J:195050 )
• cardiomegaly occurs postnatally as heart to body mass ratio is similar to controls at E18.5
