VSX2 (Visual System Homeobox 2) is a Protein Coding gene. Diseases associated with VSX2 include Microphthalmia, Isolated 2 and Microphthalmia With Coloboma 3. VSX2 encodes a homeobox protein originally described as a retina-specific transcription factor. Mutations in VSX2 are associated with microphthalmia, cataracts and iris abnormalities.
