[Interaction of the mutant aphakia, fidget and ocular retardation genes in mice].
The phenogenetic analysis of the effects of aphakia (ak) gene and its interaction with the ocular retardation (or) and fidget (fi) genes suggests that the ak gene acts in the lens cells with the result of arresting lens fibre differentiation. In mice homozygous for ak, the lens failure leads to secondary retina defects, in particular, to formation of retinal folds. In ak/ak or/or mice, the lens and retina morphogenesis stops at the optic cup stage, the eye is strongly reduced in size and more affected, compared to the corresponding single homozygotes. Unlike ak/ak or/or, in the ak/ak fi/fi mice the eyes are more regular in shape than those in the ak/ak +/+ condition. The fi gene inhibition of the retina anlage growth leads to some improvement of the eye development in double ak/ak fi/fi homozygotes, due to the absence of extensive retina folding.
