mortality/aging
• a significant portion of homozygotes die between E16.5 and E18.5
• most homozygotes die during the first 4 days of life
• only 2.6% of homozygotes are obtained at 2-3 weeks of age
• rare male and female homozygotes survive beyond 12 weeks of age

growth/size/body
• newborn homozygotes are smaller in size than wild-type or heterozygous littermates
• moribund homozygotes exhibit a wasted appearance
• however, no respiratory distress is observed
• rare postnatal survivors remain healthy but appear smaller than wild-type or heterozygous littermates
• newborn homozygotes exhibit poor postnatal weight gain
• by E16.5, homozygotes weigh significant less than wild-type controls
• at birth, a portion of homozygotes display heterotaxy with either reversal of the abdominal viscera and normal heart position or dextrocardia with normal positioning of the abdominal viscera
• at birth, 48.1% of homozygotes show reversal of the abdominal viscera and dextrocardia consistent with random determination of left-right asymmetry
• no asplenia or polysplenia is observed

nervous system
• homozygotes exhibit complete absence of cilia in the chorid plexus
• at >1 wk of age, 3 of 6 homozygotes exhibit hydrocephalus, with one of them dying at 4 weeks
• homozygotes exhibit complete absence of cilia in the chorid plexus

embryo
• at birth, 48.1% of homozygotes show reversal of the abdominal viscera and dextrocardia consistent with random determination of left-right asymmetry

behavior/neurological
• moribund homozygotes are less active than wild-type mice

reproductive system
• homozygotes exhibit complete absence of cilia in the oviduct
• mutant sperm lack flagella
• rare postnatal male and female survivors fail to reproduce

respiratory system
• homozygotes exhibit complete absence of cilia in the proximal respiratory epithelium

cardiovascular system
• at birth, 48.1% of homozygotes show dextrcardia associated with reversal of the abdominal viscera

cellular
• homozygotes exhibit complete absence of cilia in the chorid plexus
• homozygotes exhibit complete absence of cilia in the oviduct
• homozygotes exhibit complete absence of cilia in the proximal respiratory epithelium
• mutant sperm lack flagella

mortality/aging
• about 50% of homozygotes die prior to E18.5

respiratory system
• at E18.5, 10% of homozygotes display a reversal of lung laterality resulting in a single-lobed right lung and a four-lobed left lung
• Background Sensitivity: unexpectedly, 60% of E18.5 homozygotes on a mixed genetic background involving C57BL/6 and FVB/N display four lobes in both lungs; in contrast, on a C57BL/6 background, 50% of homozygotes show a normal lung pattern while the remaining 50% show a reversal lung pattern
• right pulmonary isomerism is likely due to absence of Pitx2 expression in both lateral plate mesoderms at E8.5

digestive/alimentary system
• at E18.5, 10% of homozygotes display a centrally located stomach
• at E18.5, 50% of homozygotes display a right-sided stomach

growth/size/body
• at E18.5, 50% of homozygotes display a right-sided stomach
• at E18.5, 10% of homozygotes display a reversal of lung laterality resulting in a single-lobed right lung and a four-lobed left lung

• right pulmonary isomerism is likely due to absence of Pitx2 expression in both lateral plate mesoderms at E8.5

cardiovascular system
N
• unexpectedly, all surviving homozygotes display a normal left-sided aortic arch at E18.5
• at E18.5, 3 of 10 homozygotes display an underdeveloped aorta
