Summaries for CNGA3 Gene

Entrez Gene Summary for CNGA3 Gene

  • This gene encodes a member of the cyclic nucleotide-gated cation channel protein family which is required for normal vision and olfactory signal transduction. Mutations in this gene are associated with achromatopsia (rod monochromacy) and color blindness. Two alternatively spliced transcripts encoding different isoforms have been described. [provided by RefSeq, Jul 2008]

GeneCards Summary for CNGA3 Gene

CNGA3 (Cyclic Nucleotide Gated Channel Alpha 3) is a Protein Coding gene. Diseases associated with CNGA3 include achromatopsia-2 and oligocone trichromacy. Among its related pathways are Activation of cAMP-Dependent PKA and CREB Pathway. GO annotations related to this gene include protein C-terminus binding and voltage-gated potassium channel activity. An important paralog of this gene is KCNH1.

UniProtKB/Swiss-Prot for CNGA3 Gene

  • Visual signal transduction is mediated by a G-protein coupled cascade using cGMP as second messenger. This protein can be activated by cyclic GMP which leads to an opening of the cation channel and thereby causing a depolarization of cone photoreceptors. Induced a flickering channel gating, weakened the outward rectification in the presence of extracellular calcium, increased sensitivity for L-cis diltiazem and enhanced the cAMP efficacy of the channel when coexpressed with CNGB3 (By similarity). Essential for the generation of light-evoked electrical responses in the red-, green- and blue sensitive cones.

  • Achromatopsia 2 (ACHM2) [MIM:216900]: An ocular stationary disorder due to the absence of functioning cone photoreceptors in the retina. It is characterized by total colorblindness, low visual acuity, photophobia and nystagmus. {ECO:0000269 PubMed:11536077, ECO:0000269 PubMed:14757870, ECO:0000269 PubMed:15712225, ECO:0000269 PubMed:18521937, ECO:0000269 PubMed:24903488, ECO:0000269 PubMed:9662398}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Note=Defects in CNGA3 may be a cause of Leber congenital amaurosis (LCA), 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.
