N | normal phenotype |
• mice die within the first month usually after birth 2 days after beginning to gasp for air at P16
• death is either spontaneous or precipitated by the stress of routine handling

|
• thin at P17
|
• at P8 and P20, heart weights reduced 15% and 25%, respectively, compared to in wild-type mice
• mice exhibit decreased heart weight to body weight
|
• at P17, mice exhibit an increase in left ventricle diameter of 6.7% in diastolic and 57.1% in systolic states
|
