Analysis Tools
mortality/aging
|
• mice exhibiting exencephaly die shortly after birth due to central nervous system disorder unlike wild-type mice
• fewer than expected mice are present at weaning
|
|
• some mice die between E16.5 and E18.5
|
reproductive system
 |
• the number of spermatozoa in mutant male mice is reduced to about half of that in control males
|
nervous system
|
• at E18.5, exencephalic mice exhibit bleeding from the brain unlike wild-type mice
|
|
• at E9.5, mice exhibit a 3-fold increase in apoptosis in the neuroepithelium unlike wild-type mice
|
|
• at E14.5, mice exhibit increased neural progenitor cell proliferation compared with wild-type mice
|
|
• at E9.5 and E10.5, the neural folds remain unfused, unlike in wild-type embryos
|
|
• Background Sensitivity: on a 129P2/OlaHsd and C57BL/6 background, some mice exhibit failure of neural tube closure in the midbrain and hindbrain unlike wild-type mice
|
|
• the midbrain and hindbrain are massively expanded and everted and cover the whole brain unlike in wild-type mice

vision/eye
|
• mice exhibit expanded neural retina compared with wild-type mice
|
|
• in some mice at E14.5
|
growth/size/body
|
• at E9.5, mice exhibit a 3-fold increase in apoptosis in the cranial mesenchyme unlike wild-type mice
|
|
• in adult mice
|
|
• in exencephalic mice at E18.5
