cardiovascular system
• dramatic overgrowth

growth/size/body

renal/urinary system
• kidneys may display agenesis or over growth, with both conditions often seen in the same animal
• unilateral or bilateral renal agenesis is seen in 64% of mice
• kidneys that do form have an expanded population of mesenchymal progenitor cells
• the Wolffian duct remains detached from the ureteric bud at E13.5 in some mice
• absence of ureteric bud derived structures at E13.5 in some mice
• expression analysis indicates that the metanephric mesenchyme is specified but fails to condense and undergo epithelialization
• widespread apoptosis is seen in many mice
• kidneys that do form are significantly enlarged
• absence of ureteric bud derived structures at E13.5 in some mice

• asymmetrical distribution of ossification centers
• massive increases in mineralized matrix
• decreased mineralization of the trabecular area in long bones perinatally
• massive increases in mineralized matrix in the compact bone
• deficiency in endochondral bone ossification
• delayed ossification of the long bones at E14.5
