Genes affected

TAS1R1 (HGNC:14448): (taste 1 receptor member 1) The protein encoded by this gene is a G protein-coupled receptor and is a component of the heterodimeric amino acid taste receptor T1R1+3. The T1R1+3 receptor responds to L-amino acids but not to D-enantiomers or other compounds. Most amino acids that are perceived as sweet activate T1R1+3, and this activation is strictly dependent on an intact T1R1+3 heterodimer. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jun 2010]

LOC107984912 (HGNC:):

ACMG classification

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

• BP4: Computational evidence support a benign effect (MetaRNN=0.0077606738).
• BS1: Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.00776 (1182/152284) while in subpopulation EAS AF = 0.0375 (194/5172). AF 95% confidence interval is 0.0332. There are 17 homozygotes in GnomAd4. There are 550 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 17 AR gene
