phenotype observed in females
phenotype observed in males
N normal phenotype
mortality/aging
• around two thirds of those that survive past E12 die at birth
• about half of the homozygous mutant embryos die around E11 - E12

cardiovascular system
• at E10.5 inversion of cardiac looping is seen in mutant embryos
• at E18 some mutant embryos had meso- or dextrocardia
• at E18 some mutant embryos had meso- or dextrocardia

embryo
• from E7.25 to E8.0 growth of nodal cilia is significantly delayed resulting in significantly shorter cilia in homozygous embryos
• at E10.5 inversion of embryo turning is seen
• markers that are normally expressed only on the left side are expressed on both sides

growth/size/body
• mutants are about two thirds the size of wild-type littermates at birth
• growth retardation increases as the mutant mice age with adults body weight being about half that of control littermates
• some surviving mutants have situs inversus
• at E18, some mutant embryos had situs inversus or incomplete inversion defect

cellular
• from E7.25 to E8.0 growth of nodal cilia is significantly delayed resulting in significantly shorter cilia in homozygous embryos
