rs713598 TAS2R38
Strong bitter taster (PTC/PROP). May dislike cruciferous vegetables and certain medications.
What is rs713598?
rs713598 is a single-nucleotide polymorphism (SNP) in the TAS2R38 gene (Taste receptor type 2 member 38 (bitter taste)). Each person carries two copies, one from each parent, so a result is reported as a pair of letters such as GG. The table below describes what studies associate with each genotype; the association is statistical, across populations, and is not a diagnosis.
What does each rs713598 genotype mean?
| Genotype | Association | What the evidence says | Confidence |
|---|---|---|---|
| GG | typical / lower | Strong bitter taster (PTC/PROP). May dislike cruciferous vegetables and certain medications. | 85% |
| GC / CG | typical / lower | Moderate bitter taste perception. | 80% |
| CC | typical / lower | Non-taster for PTC/PROP bitterness. | 85% |

Genetic associations describe risk across populations, not a diagnosis for any one person. Most variants shift risk modestly and act alongside lifestyle, environment and other genes. Consumer DNA chips do not read every position and can be wrong at any single one. For general education only; talk to a clinician or genetic counsellor before acting on anything here, and never change a prescribed medicine without your prescriber.
