Summaries for VSX1 Gene

Entrez Gene Summary for VSX1 Gene

  • 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]

GeneCards Summary for VSX1 Gene

VSX1 (Visual System Homeobox 1) is a Protein Coding gene. Diseases associated with VSX1 include keratoconus 1 and corneal dystrophy, posterior polymorphous, 1.

UniProtKB/Swiss-Prot

VSX1_HUMAN
  • Corneal dystrophy, posterior polymorphous, 1 (PPCD1) [MIM:122000]: A rare corneal disorder characterized by small aggregates of apparent vesicles bordered by a gray haze at the level of Descemet membrane, an altered corneal endothelial cell structure, and an unusual proliferation of endothelial cells. Symptoms can range from very aggressive to asymptomatic and non-progressive, even within the same family. {ECO:0000269 PubMed:11978762}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Keratoconus 1 (KTCN1) [MIM:148300]: Frequent corneal dystrophy with an incidence that varies from 50 to 230 per 100000. The cornea assumes a conical shape as a result of a progressive non-inflammatory thinning of the corneal stroma. Keratoconus is most often an isolated sporadic condition with cases of autosomal dominant and autosomal recessive transmission. {ECO:0000269 PubMed:11978762, ECO:0000269 PubMed:15623752, ECO:0000269 PubMed:19956409}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Craniofacial anomalies and anterior segment dysgenesis syndrome (CAASDS) [MIM:614195]: A disorder with extremely variable expressivity. Clinical features include wide interpupillary distance, abnormal corneal endothelium, unusual pinnae, partially to completely empty sella turcica, posterior fossa cyst, anterior encephalocele, and/or hydrocephalus. {ECO:0000269 PubMed:15051220}. Note=The disease is caused by mutations affecting the gene represented in this entry.
