Data Sources

IMPC Data for Ndufa9

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

embryo

failure to gastrulate ( J:279207 )

• no morphological hallmarks typical of gastrulating embryos are observed at E7.5

embryonic growth arrest ( J:279207 )

• embryos arrest prior to gastrulation

decreased embryo size ( J:279207 )

• embryos are much smaller than controls at E7.5

abnormal egg cylinder morphology ( J:279207 )

• a rudimentary egg cylinder is observed at E7.5

absent head fold ( J:279207 )

• no head folds are present at E7.5

absent primitive node ( J:279207 )

failure of primitive streak formation ( J:279207 )

• no morphological evidence of primitive streak formation is observed at E7.5

IMPC - JAX (J:211773)

MGI
