VSX1 visual system homeobox 1

Gene ID: 30813, updated on 14-Nov-2024
Gene type: protein coding
Also known as: PPD; KTCN; PPCD; RINX; KTCN1; PPCD1; CAASDS

Summary

The protein encoded by this gene contains a paired-like homeodomain and binds to the core of the locus control region of the red/green visual pigment gene cluster. The encoded protein may regulate expression of the cone opsin genes early in development. Mutations in this gene can cause posterior polymorphous corneal dystrophy and keratoconus. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Jul 2008]
