Genes affected

OR6B1 (HGNC:8354): (olfactory receptor family 6 subfamily B 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.

The c.134T>G (p.I45S) alteration is located in exon 1 (coding exon 1) of the OR6B1 gene. This alteration results from a T to G substitution at nucleotide position 134, causing the isoleucine (I) at amino acid position 45 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
