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]

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.847

Jan 16, 2024

The c.611T>C (p.L204P) alteration is located in exon 1 (coding exon 1) of the TAAR9 gene. This alteration results from a T to C substitution at nucleotide position 611, causing the leucine (L) at amino acid position 204 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
