Genes affected

TAS2R41 (HGNC:18883): (taste 2 receptor member 41) 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. Chloramphenicol is an agonist for the encoded protein. [provided by RefSeq, Jul 2017]

The c.65C>T (p.A22V) alteration is located in exon 1 (coding exon 1) of the TAS2R41 gene. This alteration results from a C to T substitution at nucleotide position 65, causing the alanine (A) at amino acid position 22 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
