• ♀: phenotype observed in females
• ♂: phenotype observed in males
• N: normal phenotype

mortality/aging

embryonic lethality during organogenesis, complete penetrance ( J:208632 )

• arrest by E9.0

embryo

absent embryonic cilia ( J:208632 )

• absent at E7.5 and E8.5

• lack cilia and basal bodies but have normal planar cell polarity in node cells

increased embryonic tissue cell apoptosis ( J:208632 )

• embryos show many pyknotic and fragmented nuclei

abnormal embryo turning ( J:208632 )

• form a heart and neural tube but fail to undergo turning

embryonic growth arrest ( J:208632 )

• by E9.0

cellular

absent embryonic cilia ( J:208632 )

• absent at E7.5 and E8.5

• lack cilia and basal bodies but have normal planar cell polarity in node cells

abnormal centrosome morphology ( J:208632 )

• disrupted organization of the centrosome in embryonic cells

abnormal mitosis ( J:208632 )

• at E8.5 a 70% increase in the fraction of mitotic cells is seen

increased embryonic tissue cell apoptosis ( J:208632 )

• embryos show many pyknotic and fragmented nuclei
