Genes affected

OR2L2 (HGNC:8266): (olfactory receptor family 2 subfamily L member 2) 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

Nov 27, 2024

The c.76G>A (p.V26I) alteration is located in exon 1 (coding exon 1) of the OR2L2 gene. This alteration results from a G to A substitution at nucleotide position 76, causing the valine (V) at amino acid position 26 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
