Genes affected

OR1L6 (HGNC:8218): (olfactory receptor family 1 subfamily L member 6) 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.

Nov 08, 2022

The c.404T>C (p.V135A) alteration is located in exon 1 (coding exon 1) of the OR1L6 gene. This alteration results from a T to C substitution at nucleotide position 404, causing the valine (V) at amino acid position 135 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
