Summary: Olfactory receptors interact with odorant molecules in the nose, to initiate a neuronal response that triggers the perception of a smell. The olfactory receptor proteins are members of a large family of G-protein-coupled receptors (GPCR) arising from single coding-exon genes. Olfactory receptors share a 7-transmembrane domain structure with many neurotransmitter and hormone receptors and are responsible for the recognition and G protein-mediated transduction of odorant signals. The olfactory receptor gene family is the largest in the genome. The nomenclature assigned to the olfactory receptor genes and proteins for this organism is independent of other organisms.

The odorant receptor OR2W3 on airway smooth muscle evokes bronchodilation via a cooperative chemosensory tradeoff between TMEM16A and CFTR.

A signal in a nearby olfactory receptor on chromosome 1, olfactory receptor family 2 subfamily L member 13 (OR2L13), tagged by rs151319968, was nominally associated with PTSD in the AI sample. Although no variants were significantly associated after correction for multiple testing in a meta-analysis of the two cohorts, pathway analysis of the top hits showed an enrichment cluster of terms related to sensory transduction.

We therefore conclude that this sequence variant, and hence the OR2W3 gene, do not cause RP. Prompted by these findings and based on simple principles of population genetics, we suggest that WES studies should consider DNA variants as the possible cause of dominant RP only if they are present in less than 1:100,000 individuals from the general population.
Title: OR2W3 sequence variants are unlikely to cause inherited retinal diseases.
This outstanding specificity of extremely narrowly tuned human OR2M3 can explain both odor qualities and odor threshold trend within a homologous series of 3-mercapto-2-methylalkan-1-ols and suggests a modern human-specific, food-related function of OR2M3 in detecting a single onion key food odorant.

OR2W3 is associated with genetic susceptibility to Japanese male infertility.

A novel missense mutation, c. 424 C > T transition (p.R142W) in OR2W3 gene, was identified as a potentially causative mutation for autosomal dominant Retinitis pigmentosa.

Our results provided a new insight into susceptibility of USF1 variant with male infertility. rs11204546 of OR2W3 and rs11677854 of GTF2A1L might be additional valuable molecular predictive markers

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
