VAX2 (Ventral Anterior Homeobox 2) is a Protein Coding gene. Diseases associated with VAX2 include Astigmatism and Corpus Callosum Agenesis. Among its related pathways are Ectoderm Differentiation. VAX2 encodes a homeobox protein and is almost exclusively expressed in the ventral portion of the retina during development. In mouse studies, VAX2 was found to be required for the correct formation of the optic fissure and other aspects of retinal development.
