|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
|
• mice that maternally inherit the mutant allele do not survive to adulthood
|
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
|
• embryos with the maternally inherited allele die neonatally
|
|
• expression of brown adipose development and function genes are altered in embryos with the maternally inherited allele, indicating compromised brown adipose tissue development
• interscapular brown adipose tissue shows disorganized morphology with large areas of lipid in E18.5 fetuses with the materanally inherited allele
• mitochondrial DNA content of interscapular brown adipose tissue in embryos with the maternally inherited allele is 40% less than the wild-type level
|
|
• E18.5 embryos with the maternally inherited allele have poorly discernable interscapular brown adipose tissue depots lacking the characteristic butterfly shape normally seen at this stage
|
|
• E18.5 embryos with the maternally inherited allele have poorly discernable interscapular brown adipose tissue depots lacking the characteristic butterfly shape normally seen at this stage
• interscapular brown adipose tissue shows disorganized morphology with large areas of lipid at E18.5
• mitochondrial DNA content of interscapular brown adipose tissue is 40% less than the wild-type level
|
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
|
• present at expected numbers at E16.5
• 30% die in utero before birth when Cdkn1ctm1Sje is maternally inherited
|
|
• half expected numbers survive to 2 weeks of age
• Background Sensitivity: significant improvement in survival beyond day 1 of heterozygotes inheriting a maternal mutant when on an outbred CD1 background
|
|
• significantly enlarged and displaying cytomegaly
|
|
• paternal allele is transcriptionally repressed
• no abnormal phenotype in crosses between heterozygous males and wild-type females
|
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
| N |
• mice that maternally inherit the mutant Cdkn1c allele do survive to adulthood
|
|
• paternal transmission of the deletion mutation leads to the paternal allelic expression of the Cdkn1c gene and prevents the postnatal lethality phenotype associated with Cdkn1c heterozygotes that paternally inherit the wild-type allele

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