Genes affected
OR2AE1 (HGNC:15087): (olfactory receptor family 2 subfamily AE member 1) 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.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 26, 2024The c.508G>A (p.G170R) alteration is located in exon 1 (coding exon 1) of the OR2AE1 gene. This alteration results from a G to A substitution at nucleotide position 508, causing the glycine (G) at amino acid position 170 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
