Description

These mice carry a spontaneous mutation at the Vsx2 locus characterized by microphthalmia, a thin hypocellular retina, and optic nerve aplasia

Detailed description

Ocular retardation (Vsx2^or-J) is a murine eye mutation causing microphthalmia, a thin hypocellular retina and optic nerve aplasia. When expressed on an inbred 129/Sv strain, the Vsx2^or-J phenotype is characterized by microphthalmia and a thin, poorly differentiated retina in which the peripheral portion is affected to a greater extent than the central portion. Such mutant retinae lack differentiated bipolar cells and the optic nerve typically fails to form, leading to blindness.

Development

The Vsx2^or-J mutation arose on a 129/Sv strain carrying wild type alleles for albino ( Tyr⁺) and pink eye (Oca2⁺). Embryos for cryopreservation were produced by mating males homozygous for Vsx2^or-J to C57BL/6J females in 1984.
