Cyclic nucleotide-gated channel alpha 3

Cyclic nucleotide-gated cation channel alpha-3 is a is_associated_with::protein that in humans is encoded by the CNGA3 is_associated_with::gene.

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. Two alternatively-spliced transcripts encoding different isoforms have been described.

Clinical relevance
Variants in this gene have been shown to cause is_associated_with::achromatopsia and colour blindness.
