Summaries for CRX Gene

Entrez Gene Summary for CRX Gene

  • The protein encoded by this gene is a photoreceptor-specific transcription factor which plays a role in the differentiation of photoreceptor cells. This homeodomain protein is necessary for the maintenance of normal cone and rod function. Mutations in this gene are associated with photoreceptor degeneration, Leber congenital amaurosis type III and the autosomal dominant cone-rod dystrophy 2. Several alternatively spliced transcript variants of this gene have been described, but the full-length nature of some variants has not been determined. [provided by RefSeq, Jul 2008]

GeneCards Summary for CRX Gene

CRX (Cone-Rod Homeobox) is a Protein Coding gene. Diseases associated with CRX include Cone-Rod Dystrophy and Leber Congenital Amaurosis 7. GO annotations related to this gene include transcription factor activity, sequence-specific DNA binding and RNA polymerase II core promoter proximal region sequence-specific DNA binding. An important paralog of this gene is PITX3.

UniProtKB/Swiss-Prot for CRX Gene

  • Transcription factor that binds and transactivates the sequence 5-TAATC[CA]-3 which is found upstream of several photoreceptor-specific genes, including the opsin genes. Acts synergistically with other transcription factors, such as NRL, RORB and RAX, to regulate photoreceptor cell-specific gene transcription. Essential for the maintenance of mammalian photoreceptors.

CRX_HUMAN
  • Cone-rod dystrophy 2 (CORD2) [MIM:120970]: An inherited retinal dystrophy characterized by retinal pigment deposits visible on fundus examination, predominantly in the macular region, and initial loss of cone photoreceptors followed by rod degeneration. This leads to decreased visual acuity and sensitivity in the central visual field, followed by loss of peripheral vision. Severe loss of vision occurs earlier than in retinitis pigmentosa. {ECO:0000269 PubMed:9390563, ECO:0000269 PubMed:9427255, ECO:0000269 PubMed:9792858}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Leber congenital amaurosis 7 (LCA7) [MIM:613829]: A severe dystrophy of the retina, typically becoming evident in the first years of life. Visual function is usually poor and often accompanied by nystagmus, sluggish or near-absent pupillary responses, photophobia, high hyperopia and keratoconus. {ECO:0000269 PubMed:20513135, ECO:0000269 PubMed:21602930, ECO:0000269 PubMed:9792858, ECO:0000269 PubMed:9931337}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Retinitis pigmentosa (RP) [MIM:268000]: A retinal dystrophy belonging to the group of pigmentary retinopathies. Retinitis pigmentosa is characterized by retinal pigment deposits visible on fundus examination and primary loss of rod photoreceptor cells followed by secondary loss of cone photoreceptors. Patients typically have night vision blindness and loss of midperipheral visual field. As their condition progresses, they lose their far peripheral visual field and eventually central vision as well. {ECO:0000269 PubMed:9427255, ECO:0000269 PubMed:9792858}. Note=The disease is caused by mutations affecting the gene represented in this entry.
