Genes affected

TACR3 (HGNC:11528): (tachykinin receptor 3) This gene belongs to a family of genes that function as receptors for tachykinins. Receptor affinities are specified by variations in the 5'-end of the sequence. The receptors belonging to this family are characterized by interactions with G proteins and 7 hydrophobic transmembrane regions. This gene encodes the receptor for the tachykinin neurokinin 3, also referred to as neurokinin B. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Likely_benign. Variant got -6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.93).
• BS1: Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.000402 (61/151864) while in subpopulation SAS AF= 0.00995 (48/4822). AF 95% confidence interval is 0.00771. There are 0 homozygotes in gnomad4. There are 47 alleles in male gnomad4 subpopulation. This position pass quality control queck.
