Genes affected

TAS2R3 (HGNC:14910): (taste 2 receptor member 3) 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. These apparently intronless taste receptor genes encode 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]

TAS2R3 links:

SSBP1 (HGNC:11317): (single stranded DNA binding protein 1) SSBP1 is a housekeeping gene involved in mitochondrial biogenesis (Tiranti et al., 1995 [PubMed 7789991]). It is also a subunit of a single-stranded DNA (ssDNA)-binding complex involved in the maintenance of genome stability (Huang et al., 2009) [PubMed 19683501].[supplied by OMIM, Feb 2010]

Ambry Genetics

May 11, 2022

The c.16G>A (p.E6K) alteration is located in exon 1 (coding exon 1) of the TAS2R3 gene. This alteration results from a G to A substitution at nucleotide position 16, causing the glutamic acid (E) at amino acid position 6 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
