Genes affected
CNGA2 (HGNC:2149): (cyclic nucleotide gated channel subunit alpha 2) The protein encoded by this gene represents the alpha subunit of a cyclic nucleotide-gated olfactory channel. The encoded protein contains a carboxy-terminal leucine zipper that mediates channel formation. [provided by RefSeq, Jan 2010]
