Incidental mutations (data from Mutagenetix , APF )
Homozygotes for some targeted null mutations exhibit defects of the yolk sac and placenta, lack circulating erythrocytes, and die at midgestation. Mutant endothelial cells show enhanced proliferation, improper migration, and reduced fibronectin production.
