Cyclic nucleotide-gated cation channel alpha-3 is a protein that in humans is encoded by the CNGA3 gene.^[5]^[6]^[7]^[8]

Function

This gene encodes a member of the cyclic nucleotide-gated cation channel protein family, which is required for normal vision and olfactory signal transduction. CNGA3 is expressed in cone photoreceptors and is necessary for color vision.^[9] Missense mutations in this gene are associated with rod monochromacy and segregate in an autosomal recessive pattern.^[9] Two alternatively-spliced transcripts encoding different isoforms have been described.^[8]

Clinical relevance

Variants in this gene have been shown to cause achromatopsia^[10] and colour blindness.
