mortality/aging
• homozygotes die shortly after E9.5, often encapsulated and undergoing reabsorption by E12.5
|
embryo
• homozygotes stop developing at ~E9.5
|
• at E9.5, homozygotes show a highly penetrant closure defect in the anterior craniofacial region of the neural tube, at the level of the forebrain/midbrain boundary
• however, the spinal cord and rostral extremity of the forebrain appear unaffected
|
nervous system
• at E9.5, homozygotes show a highly penetrant closure defect in the anterior craniofacial region of the neural tube, at the level of the forebrain/midbrain boundary
• however, the spinal cord and rostral extremity of the forebrain appear unaffected
