Variant summary

Our verdict is Benign. Variant got -12 ACMG points: 0P and 12B. BP4_Strong BS1 BS2

The NM_175057.4(TAAR9):c.832G>A(p.Ala278Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0449 in 1,563,556 control chromosomes in the GnomAD database, including 1,818 homozygotes. In-silico tool predicts a benign outcome for this variant. 10/13 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another nucleotide change resulting in same amino acid change has been previously reported as Likely benignin UniProt.

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 Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0019289851).
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0372 (5658/152276) while in subpopulation NFE AF= 0.0514 (3494/68010). AF 95% confidence interval is 0.05. There are 160 homozygotes in gnomad4. There are 2839 alleles in male gnomad4 subpopulation. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd at 160 AR gene
