Genes affected

TAS1R3 (HGNC:15661): (taste 1 receptor member 3) The protein encoded by this gene is a G-protein coupled receptor involved in taste responses. The encoded protein can form a heterodimeric receptor with TAS1R1 to elicit the umami taste response, or it can bind with TAS1R2 to form a receptor for the sweet taste response.

Ambry Genetics

Apr 22, 2022

The c.530G>A (p.R177Q) alteration is located in exon 3 (coding exon 3) of the TAS1R3 gene. This alteration results from a G to A substitution at nucleotide position 530, causing the arginine (R) at amino acid position 177 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
