Homozygous mutant mice show embryogenesis defects in frontonasal mass, first branchial arch and somites, and vascular, cardiac and skeletal muscle defects causing growth retardation, muscle weakness, abnormal posture, and premature death ranging from embryonic day 11.5 to 8 weeks of age. A homozygous point mutation leads to reduced systolic function and mild ventricular dilation in the heart and increased cardiomyocyte size.
