Mouse lines carrying:
Snx2tm1Mag mutation (1 available); any Snx2 mutation (43 available)
Vps26atm1Cos mutation (1 available); any Vps26a mutation (32 available)
♀ phenotype observed in females
♂ phenotype observed in males
N normal phenotype
mortality/aging
lethality throughout fetal growth and development, incomplete penetrance ( J:102476 )
• 90% die during development with live embryos recovered as late as E18.5; the 10% that survive do not exhibit hemorrhage or exencephaly and are viable and fertile

cardiovascular system
hemorrhage ( J:102476 )
• embryos at E18.5 exhibit hemorrhage at different sites; occasionally seen in the head with accompanying exencephaly whereas others show blood in the abdomen

nervous system
exencephaly ( J:102476 )
• seen occasionally at E18.5

craniofacial
abnormal craniofacial morphology ( J:102476 )
• craniofacial abnormalities
