Atf4tm1Jml mutation (0 available); any Atf4 mutation (21 available)
phenotype observed in females
phenotype observed in males
N normal phenotype
mortality/aging
• partial penetrance: the number of E18.5 to P1 mutants is reduced and only 30% of homozygotes survive until adulthood

growth/size/body
• surviving homozygotes are runted
• E17.5 mutants are runted

vision/eye
• small and malformed
• small and malformed
• lens development is normal between E12.5 and 14.5, however by E15.5-16.5, the anterior lens cells undergo massive and synchronous apoptosis resulting in the absence of the lens in adults

vision/eye
N
• eye and eyelid morphology are normal and there is a marked suppression in the microphthalmia that is seen in single Atf4 homozygotes
• lenses are present, however they show an increased number of cells in the bow region
• decrease in numbers of lens fiber cells
