Genes affected

TAAR9 (HGNC:20977): (trace amine associated receptor 9) TAAR9 is a member of a large family of rhodopsin G protein-coupled receptors (GPCRs, or GPRs). GPCRs contain 7 transmembrane domains and transduce extracellular signals through heterotrimeric G proteins.[supplied by OMIM, Jul 2005]

Collection Method: clinical testing

The c.374G>C (p.C125S) alteration is located in exon 1 (coding exon 1) of the TAAR9 gene. This alteration results from a G to C substitution at nucleotide position 374, causing the cysteine (C) at amino acid position 125 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
