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.

Jun 07, 2023

The c.260C>T (p.S87L) alteration is located in exon 2 (coding exon 2) of the TAS1R3 gene. This alteration results from a C to T substitution at nucleotide position 260, causing the serine (S) at amino acid position 87 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
