mortality/aging
• normal numbers of hemizygotes atE16.5
• hemizygotes reduced from 26% to 16% by weaning

growth/size/body
• ventral wall closure defects with incomplete penetrance
• medullary cystic dysplasia
• males are 30% larger than controls
• females show intermediate growth properties

renal/urinary system
• medullary cystic dysplasia
• medullary cystic dysplasia

skeleton
• reduced conversion of macrophage precursors to osteoclasts
• bifurcated
• 45% of mice show defects in endochondral ossification
• persistence of hypertrophic chondrocytes at E16.5 when controls have replaced chondrocytes with trabecular bone

hematopoietic system
• reduced conversion of macrophage precursors to osteoclasts

immune system
• reduced conversion of macrophage precursors to osteoclasts

embryo
• small to moderate umbilical hernias

cardiovascular system
• seen in one P0 mutant mouse
• at E13.5 mutant embryos show a delay in the development of the coronary vascular plexus
• at E13.5, there are approximately five times as many intramyocardial (arterial) vessels in the mutant as in controls, whereas the number of subepicardial (venous) vessels tended to be less; loss of Gpc3 function causes a disproportionate increase in the number of coronary arteries relative to veins
• at PO, coronary artery fistulas are seen in 3 of 16 mutant animals; some Gpc3-deficient animals had a dilated left anterior descending coronary artery feeding a coronary artery fistula that coursed through the interventricular septum and drained into the right ventricle
• seen in one P0 mutant mouse; the pulmonic valve was ventral and leftward to the aortic valve, which also arose from the right ventricle
• at P0, two mutant animals had a common atrioventricular canal with leaflets of the common valve bridging the two ventricles
• at P0, two mutant animals had a common atrioventricular canal with leaflets of the common valve bridging the two ventricles
• at P0, some mutant hearts exhibit VSD (5/16 hearts; 4 perimembranous, 1 inlet)

cellular
• seen in one P0 mutant mouse
• reduced conversion of macrophage precursors to osteoclasts
