mortality/aging

prenatal lethality, incomplete penetrance ( J:154303 )

• fewer than expected mice are produced from heterozygous parents even when the deficit of maternal care is corrected with fostering

cardiovascular system

abnormal heart development ( J:154303 )

• some embryos exhibit cardiac development defects unlike wild-type mice

decreased cardiac muscle contractility ( J:154303 )

• mice exhibit decreased fractional shortening compared with wild-type mice

abnormal myocardial fiber physiology ( J:154303 )

• cardiomyocyte sarcomeric function is decreased with impaired velocity of contraction and relaxation compared to in wild-type mice

• however, intracellular calcium is unchanged

homeostasis/metabolism

impaired exercise endurance ( J:154303 )

• mice exhibit decreased exercise endurance compared with wild-type mice

behavior/neurological

abnormal maternal behavior ( J:154303 )

♀ • poor maternal care is more pronounced than in heterozygous mice

impaired exercise endurance ( J:154303 )

• mice exhibit decreased exercise endurance compared with wild-type mice

embryo

embryonic growth arrest ( J:154303 )

• some embryos exhibit evidence of overall developmental failure

muscle

decreased cardiac muscle contractility ( J:154303 )

• mice exhibit decreased fractional shortening compared with wild-type mice
