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]

Sep 27, 2021

The c.106G>A (p.G36R) alteration is located in exon 1 (coding exon 1) of the TAS1R1 gene. This alteration results from a G to A substitution at nucleotide position 106, causing the glycine (G) at amino acid position 36 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
