Genes affected

TAAR6 (HGNC:20978): (trace amine associated receptor 6) This gene encodes a seven-transmembrane G-protein-coupled receptor that likely functions as a receptor for endogenous trace amines. Mutations in this gene may be associated with schizophrenia.[provided by RefSeq, Feb 2010]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -12 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.0033866167).

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.0057 (868/152228) while in subpopulation AFR AF = 0.0198 (822/41522). AF 95% confidence interval is 0.0187. There are 12 homozygotes in GnomAd4. There are 415 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 12 AR gene
