mortality/aging
prenatal lethality, incomplete penetrance ( J:103556 )
• about 40% do not survive development

growth/size/body
embryonic growth retardation ( J:103556 )
• embryos are smaller and growth retarded by E11.5
decreased embryo size ( J:103556 )
• embryos are smaller by E11.5
decreased body size ( J:103556 )
• those that survive development are born runted (about 20% smaller) due to developmental growth retardation, with small size continuing into adulthood

embryo
embryonic growth retardation ( J:103556 )
• embryos are smaller and growth retarded by E11.5
