phenotype observed in females
phenotype observed in males
N normal phenotype
mortality/aging
• only 8 of 128 mice delivered survived to adulthood
• most (120 of 128) mice die between P0.5 and P2

growth/size/body
• at 2 months of age, 2 of 8 survivors display malocclusion
• at 2 months of age, 2 of 8 survivors display an obviously bent nose
• starting at E10.5
• all mice are born smaller in size
• mice surviving to adulthood show severe growth retardation within the first 4 weeks after birth
• at E14.5-E18.5
• mice show growth retardation as early as E10.5

behavior/neurological
• pups lack gastric milk, suggesting death from starvation
• although pups are capable of actively searching and licking their mothers' nipples, they fail to remain stably attached to the nipples for even just 1 min in ~70% of attempts

skeleton
• at 2 months of age, rare survivors display bone loss in metopic sutures
• at 2 months of age, 2 of 8 survivors display malocclusion
• at 2 months of age, 2 of 8 survivors display an obviously bent nose
• at P0, neonates show delayed ossification at the nasal bones and sagittal and metopic sutures

craniofacial
• at 2 months of age, rare survivors display bone loss in metopic sutures
• at 2 months of age, 2 of 8 survivors display malocclusion
• at 2 months of age, 2 of 8 survivors display an obviously bent nose

cellular
• ESCs derived from mutant mice fail to efficiently establish H3K9me2 during retinoic acid-induced differentiation across a large number of genes, and a subset of these genes, including Oct4 and Nanog, display delayed gene silencing during differentiation

embryo
• starting at E10.5

respiratory system
• at 2 months of age, 2 of 8 survivors display an obviously bent nose
