Genes affected

TAS2R7 (HGNC:14913): (taste 2 receptor member 7) This gene product belongs to the family of candidate taste receptors that are members of the G-protein-coupled receptor superfamily. These proteins are specifically expressed in the taste receptor cells of the tongue and palate epithelia. They are organized in the genome in clusters and are genetically linked to loci that influence bitter perception in mice and humans. In functional expression studies, they respond to bitter tastants. This gene maps to the taste receptor gene cluster on chromosome 12p13. [provided by RefSeq, Jul 2008]

Ambry Genetics

Dec 06, 2022

The c.262T>C (p.F88L) alteration is located in exon 1 (coding exon 1) of the TAS2R7 gene. This alteration results from a T to C substitution at nucleotide position 262, causing the phenylalanine (F) at amino acid position 88 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
