Genes affected

OR56A5 (HGNC:14792): (olfactory receptor family 56 subfamily A member 5) 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.

Ambry Genetics

Jun 22, 2023

The c.670A>G (p.I224V) alteration is located in exon 1 (coding exon 1) of the OR56A5 gene. This alteration results from a A to G substitution at nucleotide position 670, causing the isoleucine (I) at amino acid position 224 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
