mortality/aging
• hemizygous progeny are born at less than one-third the expected Mendelian frequency, most dying by 16.5 days post coitum (16.5 dpc)
|
nervous system
• hemizygous embyros examined at 9.5 dpc often exhibit midline forebrain defects and other aspects of holoprocencephaly
• some hemizygotes that survive to birth exhibit holoprosencephalic phenotypes of varying severity
|
vision/eye
• some hemizygous embryos and liveborn pups exhibit structural eye defects
