NCIt definition : Human CNGA3 wild-type allele is located in the vicinity of 2q11.2 and is approximately
52 kb in length. This allele, which encodes cyclic nucleotide-gated cation channel
alpha-3 protein, plays a role in G-protein coupled signaling and cation transport
that modulates both vision and olfaction. Mutation of the gene is associated with
achromatopsia 2.;
NCIt note : A homozygous missense mutation in the CNGA3 gene may be associated with Leber congenital
amaurosis. (OMIM);
