Genes affected

OR2C3 (HGNC:15005): (olfactory receptor family 2 subfamily C member 3) 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.

OR2C3 links:

GCSAML (HGNC:29583): (germinal center associated signaling and motility like) This gene encodes a protein thought to be a signaling molecule associated with germinal centers, the sites of proliferation and differentiation of mature B lymphocytes. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Aug 2013]

The c.485C>G (p.T162R) alteration is located in exon 2 (coding exon 1) of the OR2C3 gene. This alteration results from a C to G substitution at nucleotide position 485, causing the threonine (T) at amino acid position 162 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
