Genes affected

TAS2R1 (HGNC:14909): (taste 2 receptor member 1) This gene encodes a member of a family of candidate taste receptors that are members of the G protein-coupled receptor superfamily and that are specifically expressed by taste receptor cells of the tongue and palate epithelia. This intronless taste receptor gene encodes a 7-transmembrane receptor protein, functioning as a bitter taste receptor. This gene is mapped to chromosome 5p15, the location of a genetic locus (PROP) that controls the detection of the bitter compound 6-n-propyl-2-thiouracil. [provided by RefSeq, Jul 2008]

The c.180G>T (p.L60F) alteration is located in exon 1 (coding exon 1) of the TAS2R1 gene. This alteration results from a G to T substitution at nucleotide position 180, causing the leucine (L) at amino acid position 60 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
