MGI Phenotype FUNCTION: This gene encodes a transmembrane protein that is a subunit of the nucleotide-gated olfactory ion channel. Knock out of this gene affects development of the olfactory epithelium and olfactory bulb. [provided by RefSeq, May 2015]
PHENOTYPE: Mice homozygous for a knock-out allele exhibit postnatal lethality within 2 days of birth, growth retardation, and abnormal olfactory neuron response to forskolin. [provided by MGI curators]
