N | normal phenotype |
• from heterozygote x wild-type matings, only 36% of offspring are heterozygous compared to the expected 50%
|
N |
• adult hearts do not show morphological abnormalities such as right ventricular outflow obstruction, atrial septal defect, or patent foramen ovale
• left ventricle structure and contractile function show no significant differences from littermate controls
|
• all mutants studied display inducible or spontaneous ventricular tachycardia (VT) compared to no wild-type hearts
|
• conduction velocity in both longitudinal (CVmax) and transverse directions (CVmin) is significantly reduced compared to littermate controls
|
• ratio of R wave/P wave amplitude is significantly reduced
|
• amplitude is diminished
|
• >90% of heterozygotes display hind-limb syndactyly
