phenotype observed in males
N normal phenotype
mortality/aging
• mice are born dead or die within hours after birth indicating perinatal lethality

growth/size/body
• embryos are approximately 20% smaller from E10.5
• approximately 20% smaller

embryo
• embryos are approximately 20% smaller from E10.5

immune system
• mice show increased expression of interferon-stimulated genes indicating innate immune activation of IFN-stimulated genes
• however, no inflammation is seen in various tissues, including the brain
• mouse embryo fibroblasts are highly refractory to vesicular stomatitis virus infection

nervous system
N
• no abnormalities are seen in the brain

mortality/aging
• mice are either perinatal lethal or survive after birth; survival is at 6% of expected frequency with 2% of pups surviving weaning

growth/size/body
• surviving mice are about 70% in body size and weight compared to controls
• surviving mice are about 70% in body size and weight compared to controls

pigmentation
• white patches show lack of melanin in hair shafts
• however, skin histology from white patches in normal
• all viable mice present a ventral white spotting phenotype and white hind- and forepaws from birth which remains through life

cellular
• E13.5 and E15.5 embryos exhibit increased LINE-1 retroelement DNA levels in cytosolic extract, however, no elevation in L1 ORF1 protein is seen

integument
• white patches show lack of melanin in hair shafts
• however, skin histology from white patches in normal
• all viable mice present a ventral white spotting phenotype and white hind- and forepaws from birth which remains through life

reproductive system
• mice fail to produce offspring

immune system
N
• no abnormalities or inflammation in internal organs, including the brain, are seen in viable mice and expression of interferon-stimulated genes is restored to normal levels
