Cyclic nucleotide gated channels are mostly found in photoreceptor and olfactory cells. For more information check PMID 12087135. The genes are listed with aliases in parentheses, full names and links to gene report pages:

Cnga1 (CNCG1, RCNC1) – cyclic nucleotide gated channel alpha 1
Cnga2 (CBCA1, CNG2) – cyclic nucleotide gated channel alpha 2
Cnga3 (CNG3, CCNC1, CNCG3) – cyclic nucleotide gated channel alpha 3
Cnga4 (CNG5, CNCA2, CNGB2, CNG4) – cyclic nucleotide gated channel alpha 4
Cngb1 (GAR1, GARP, CNCG2, RP45) – cyclic nucleotide gated channel beta 1
Cngb3 (ACHM1, ACHM3) – cyclic nucleotide gated channel beta 3
