mortality/aging
embryonic lethality during organogenesis, incomplete penetrance ( J:121748 )
• no homozygous mice are born; analysis of embryos show that majority die at midgestation with many resorptions observed, but homozygous embryos are identified at 13, 15, and 17 days post coitum in contrast to previous reports in which no homozygous null embryos are found at these time points
prenatal lethality, complete penetrance ( J:121748 )
• no homozygous mice are born

embryo
decreased embryo size ( J:121748 )
• most embryos are smaller than wild-type or heterozygous embryos
open neural tube ( J:121748 )
• one embryo was found to have an open neural tube at E12.5, similar to reports for homozygous null embryos

growth/size/body
decreased embryo size ( J:121748 )
• most embryos are smaller than wild-type or heterozygous embryos

nervous system
open neural tube ( J:121748 )
• one embryo was found to have an open neural tube at E12.5, similar to reports for homozygous null embryos

integument
pallor ( J:121748 )
• most embryos are paler than wild-type or heterozygous embryos

renal/urinary system
kidney cyst ( J:121748 )
• heterozygotes develop renal cysts after 1 year of age, but no renal tumors were identified like in reports for homozygous nulls by 1 year of age
