Genes affected

OR10J3 (HGNC:14992): (olfactory receptor family 10 subfamily J 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. This gene is considered a pseudogene because the encoded protein is truncated and missing the last transmembrane domain in several mammals.[provided by RefSeq, Jun 2021]

The c.532T>A (p.F178I) alteration is located in exon 1 (coding exon 1) of the OR10J3 gene. This alteration results from a T to A substitution at nucleotide position 532, causing the phenylalanine (F) at amino acid position 178 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
