cardiovascular system

decreased myocardial fiber size ( J:96823 )

• cardiomyocytes were 19% smaller than in wildtype

growth/size/body

decreased body size ( J:96823 )

• reduced body size with smaller liver and heart and a 14% reduction in brain size that was proportional to the reduction in body size

liver/biliary system

decreased hepatocyte number ( J:96823 )

• decreased number of cells in the liver

muscle

decreased myocardial fiber size ( J:96823 )

• cardiomyocytes were 19% smaller than in wildtype

nervous system

abnormal brain morphology ( J:96823 )

mortality/aging

postnatal lethality, incomplete penetrance ( J:72176 )
