Genes affected
TAS2R60 (HGNC:20639): (taste 2 receptor member 60) This gene encodes a member of the bitter taste receptor family which belong to the G protein-coupled receptor superfamily and are predominantly expressed in taste receptor cells of the tongue and palate epithelia. This intronless taste receptor gene encodes a seven-transmembrane receptor protein, functioning as a bitter taste receptor. This gene is clustered together with eight other taste receptor genes on chromosome 7. [provided by RefSeq, Jul 2017]
EPHA1-AS1 (HGNC:27799): (EPHA1 antisense RNA 1)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 28, 2023The c.604T>G (p.W202G) alteration is located in exon 1 (coding exon 1) of the TAS2R60 gene. This alteration results from a T to G substitution at nucleotide position 604, causing the tryptophan (W) at amino acid position 202 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
