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

growth/size/body

decreased embryo size ( J:79882 )

• beginning at E14.5, mice carrying a paternally-inherited allele are smaller than wild-type mice

decreased body weight ( J:79882 )

• mice carrying a paternally-inherited allele weigh 20%-25% less than wild-type littermates up to 6 weeks of age

• weight so internal organs (kidney, liver and lung) are decreased proportional to weight reduction

embryo

decreased embryo size ( J:79882 )

• beginning at E14.5, mice carrying a paternally-inherited allele are smaller than wild-type mice

liver/biliary system

decreased liver weight ( J:79882 )

• in mice carrying a paternally-inherited allele

renal/urinary system

decreased kidney weight ( J:79882 )

• in mice carrying a paternally-inherited allele

respiratory system

decreased lung weight ( J:79882 )

• in mice carrying a paternally-inherited allele

cellular

maternal imprinting ( J:79882 )

• mice do not exhibit defects when the allele is inherited maternally

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

embryo

embryo phenotype ( J:130399 )

N	• no embryonic lethality is observed in mice maternally inheriting the chromosome deletion

cellular

abnormal imprinting ( J:130399 )

• embryonic lethality associated with maternal transmission of the chromosome deletion is prevented by the addition of the targeted mutation due to a lack of paternal imprinting of genes in the distal portion of chromosome 7

embryo

embryo phenotype ( J:130399 )

N	• no embryonic lethality is observed in mice maternally inheriting the Ascl2^tm1Alj allele

cellular

abnormal imprinting ( J:130399 )

• embryonic lethality associated with maternal transmission of Ascl2^tm1Alj allele is prevented by the addition of the Kcnq1^tm1.1Mjh allele due to a lack of paternal imprinting of genes in the distal portion of chromosome 7
