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
|
heterotaxia
(
J:50025
)
• 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
|
hydrocephaly
(
J:50025
)
• 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
|
infertility
(
J:50025
)
• rare postnatal male and female survivors fail to reproduce
|
respiratory system
• homozygotes exhibit complete absence of cilia in the proximal respiratory epithelium
|
cardiovascular system
dextrocardia
(
J:50025
)
• 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
