vision/eye
• at E12.5 there is no evidence of expected ganglion cell differentiation
|
• at weaning, mice have a layer of connective tissue in place of the optic nerve
|
small lens
(
J:5767
)
• lens is reduced in size and fills most of eyecup
|
• in comparison to wild-type only a few necrotic sites are observed in retinal anlage at E12 and existing necrotic sites are restricted to optic stalk
|
• hyaloid artery is reduced in homozygotes at E11.5
|
• homozygotes exhibit delayed lens formation
|
• by E12 the optic fissure has a thickened inner wall and appears as a plug of retinal layer material
|
• stalk is reduced in size or absent by E13
(J:5767)
• formation of the optic stalk fissure is delayed and remained abnormal
(J:5966)
|
microphthalmia
(
J:5767
)
• small eyes are observed by E12
|
• retinal layers are uneven and normal cell layers are missing
|
nervous system
• at E12.5 there is no evidence of expected ganglion cell differentiation
|
• at weaning, mice have a layer of connective tissue in place of the optic nerve
|
pigmentation
cellular
• at E10.5 the retinas of mutant mice show no evidence of cell death compared with retinas of normal mice where zones of cell necrosis are obvious
• at E12.5 necrotic foci in mutant retinas far exceed the number found in wild-type mice
|
cardiovascular system
• hyaloid artery is reduced in homozygotes at E11.5
