Mutation description

• Allele Type: Targeted (Null/knockout)
• Mutations: Insertion, Intragenic deletion
• Mutation details: A PGK-neomycin cassette replaced the second exon, which encodes the first two helices and part of the third helix of the homeodomain. Gene targeting was confirmed by RT-PCR analysis. (J:74241)

Notes

Vax2 heterozygotes are fertile, viable and inditiguishable from wild-type. The homozygous mutant embryo shows incomplete closure of the optic fissure leading to coloboma and abnormal projection of the retinal ganglions. Teh mutant was carried on both a mixed 129/CD1 and a mixed 129/C57Bl6 background.
