cx2

• Allelic Composition: Nuak1^tm1Sia/Nuak1^tm1Sia; Nuak2^tm1Sia/Nuak2^tm1Sia
• Genetic Background: involves: C57BL/6NCrlj * CBA/JNCrlj

nervous system

abnormal neural plate morphology ( J:185597 )

• the median hinge point forms but the paired dorsolateral hinge points fail to form in the lower spine

• in the more caudal the neural plate is scarcely bent

• inefficient neural plate thickening

abnormal embryonic neuroepithelium morphology ( J:185597 )

• failure of apical constriction after the 5 somite stage

• poor development of stable microtubules

• inefficient apical constriction and apico-basal elongation of neuroepithelial cells at the cranial layer

spina bifida ( J:185597 )

• in all embryos

• neither closure 2 nor 3 took place; however, closure 1 takes place and spreads caudally but not rostrally

wavy neural tube ( J:185597 )

• undulated in the closed section

exencephaly ( J:185597 )

• in all embryos

vision/eye

abnormal retina pigment epithelium morphology ( J:185597 )

• overgrowth of the retinal pigment epithelium

abnormal optic fissure closure ( J:185597 )

• failure of optic fissure closure

abnormal retina neuronal layer morphology ( J:185597 )

• overgrowth of the neural retina

craniofacial

facial cleft ( J:185597 )

• in all embryos

growth/size/body

facial cleft ( J:185597 )

• in all embryos

abnormal body wall morphology ( J:185597 )

• body wall defects similar to those in Nuak1^tm1Sia single homozygotes

pigmentation

abnormal retina pigment epithelium morphology ( J:185597 )

• overgrowth of the retinal pigment epithelium
