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.733A>T (p.I245F) alteration is located in exon 1 (coding exon 1) of the TAS2R16 gene. This alteration results from a A to T substitution at nucleotide position 733, causing the isoleucine (I) at amino acid position 245 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
