While the function of the gene Eya3 in vertebrates is only partially understood, mutations in the Drosophila ortholog eyes absent lead to severe defects in eye development. A detailed gene expression analysis in mice suggested pleiotropic effects. Surprisingly, the characterization of Eya3-deficient mice did not show ocular defects. But, phenotypical characterization demonstrated an impact of Eya3 on growth, cardiac and muscle function as well as locomotor activity. Comparative studies in zebrafish by expression analysis and a morpholino knockdown of eya3 displayed similar results as in mice and, different from Xenopus, no affection of neurogenesis was detectable during early developmental stages.
