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.

The c.373A>G (p.I125V) alteration is located in exon 2 (coding exon 2) of the TAS1R3 gene. This alteration results from a A to G substitution at nucleotide position 373, causing the isoleucine (I) at amino acid position 125 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
