Genes affected

TAS2R16 (HGNC:14921): (taste 2 receptor member 16) This gene encodes a member of a family of candidate taste receptors that are members of the G protein-coupled receptor superfamily. These family members are specifically expressed by taste receptor cells of the tongue and palate epithelia. Each of these apparently intronless genes encodes a 7-transmembrane receptor protein, functioning as a bitter taste receptor. This gene is clustered with another 3 candidate taste receptor genes in chromosome 7 and is genetically linked to loci that influence bitter perception. [provided by RefSeq, Jul 2008]

The c.44T>C (p.V15A) alteration is located in exon 1 (coding exon 1) of the TAS2R16 gene. This alteration results from a T to C substitution at nucleotide position 44, causing the valine (V) at amino acid position 15 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
