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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 03, 2022The c.379G>A (p.A127T) alteration is located in exon 2 (coding exon 2) of the TAS1R3 gene. This alteration results from a G to A substitution at nucleotide position 379, causing the alanine (A) at amino acid position 127 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
