Gene details
- HGNC symbol
- TAS2R3
- Aliases
- T2R3
- Common name
- taste 2 receptor member 3
- Description
- 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]

- Study Design
- Using a tagging approach, the possible associations between longevity and the common genetic variation at the three bitter taste receptor gene clusters on chromosomes 5, 7 and 12 in a population of 941 unrelated individuals (20-106 years old) was investigated. The study included 348 very elderly cases (>=85 years, mean age 93.82 years, median age 92) and 593 non-elderly controls (<85 years, mean age 59.17 years, median age 67 years).
- Conclusions
- None of the tested single nucleotide polymorphisms, excepting rs978739, showed a significant association with the longevity phenotype
- Indentifier
- rs11763979
