Gene Gene information from NCBI Gene database.
Entrez ID 1261
Gene name Cyclic nucleotide gated channel subunit alpha 3
Gene symbol CNGA3
Synonyms (NCBI Gene)
ACHM2CCNC1CCNCaCCNCalphaCNCG3CNG3
Chromosome 2
Chromosome location 2q11.2
Summary 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.
