Morf4l1tm1Kto mutation (0 available); any Morf4l1 mutation (51 available)
♀ phenotype observed in females
♂ phenotype observed in males
N normal phenotype
mortality/aging
perinatal lethality, complete penetrance ( J:97640 )
• only 6.7% of pups at birth are homozygous and these die shortly after birth; however the expected number of homozygous embryos are found at E14.5

muscle

respiratory system
abnormal pulmonary alveolus morphology ( J:97640 )
• alveolar space is significantly reduced in neonates
respiratory failure ( J:97640 )
• the lungs do not appear to inflate after birth

cardiovascular system
visceral vascular congestion ( J:97640 )
• congestion of the liver, lung, and spleen
cardiac hypertrophy ( J:97640 )
• at E14.5 and at birth hypertrophy of the ventricles and atria is seen

cellular
decreased cell proliferation ( J:97640 )
• cell proliferation in homozygous embryos is reduced by 20% to 30% depending on the tissue examined
• MEFs from E13.5 embryos display a significantly lower growth rate and earlier senescence compared to wild-type MEFs

homeostasis/metabolism
skin edema ( J:97640 )
• edema is seen under the skin

growth/size/body
cardiac hypertrophy ( J:97640 )
• at E14.5 and at birth hypertrophy of the ventricles and atria is seen
decreased fetal size ( J:97640 )
• at E14.5 embryos are significantly smaller and almost all major organs are proportionally smaller

hematopoietic system

immune system

liver/biliary system

integument
skin edema ( J:97640 )
• edema is seen under the skin
abnormal epidermis stratum basale morphology ( J:97640 )
• cell number and proliferation are reduced; however apoptosis is normal
pallor ( J:97640 )
• at E14.5 homozygotes are pale
thin skin ( J:97640 )
• the skin is thinner and less keratinized
