• Allelic Composition: Grb10^{Gt(Betageo)1Ward}/Grb10⁺
• Genetic Background: involves: C57BL/6 * CBA

• ♀: phenotype observed in females
• ♂: phenotype observed in males
• N: normal phenotype

mortality/aging

perinatal lethality, incomplete penetrance ( J:84425 )

• approximately 12% of mice with a maternally inherited allele die shortly after birth

cellular

paternal imprinting ( J:84425 )

• only heterozygotes inheriting the allele from the mother display a phenotype

embryo

enlarged placenta ( J:84425 )

• the size of the placenta is increased ~30% relative to wild-type

growth/size/body

increased birth body size ( J:84425 )

• neonates are ~30% larger than wild-type

increased fetal size ( J:84425 )

• embryonic overgrowth resulting in neonates that are ~30% larger than wild-type

enlarged liver ( J:84425 )

• disproportionate overgrowth of the liver
