Genes affected

TAS2R5 (HGNC:14912): (taste 2 receptor member 5) This gene encodes a bitter taste receptor; bitter taste receptors are members of the G protein-coupled receptor superfamily and are specifically expressed by taste receptor cells of the tongue and palate epithelia. Each of these apparently intronless taste receptor genes encodes a 7-transmembrane receptor protein, functioning as a bitter taste receptor. This gene is clustered with another 3 candidate taste receptor genes on chromosome 7 and is genetically linked to loci that influence bitter perception. [provided by RefSeq, Jul 2008]

The c.121T>C (p.W41R) alteration is located in exon 1 (coding exon 1) of the TAS2R5 gene. This alteration results from a T to C substitution at nucleotide position 121, causing the tryptophan (W) at amino acid position 41 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
