rs10246939
TAS2R38rs10246939 is a single-nucleotide polymorphism (SNP) in the TAS2R38 gene. Genespiral reads it in the Personality analysis to describe Food Neophobia.

An rsID such as rs10246939 is the reference number dbSNP assigns to one position in the genome where people commonly differ by a single letter. Raw data exports from 23andMe and AncestryDNA list your two alleles at that position as a genotype - for this marker one of CC, CT, TT. The order of the two letters carries no meaning, so CT and its reverse are the same genotype.
Alleles on this page are written on the forward (plus) strand, matching how consumer raw files report them. Other references sometimes describe the same variant on the opposite strand, which swaps A↔T and C↔G - see why the same variant can look different. The associations below are educational summaries of published research; they are not diagnoses, and the effect of any single SNP is usually modest.
Food Neophobia
Behavioral Traits · Part of the Personality analysis
Linked to taste receptors, impacting willingness to try new foods and sensitivity to bitter tastes.
| Genotype | Association |
|---|---|
| CC | More neophobic |
| CT | Moderately neophobic |
| TT | Less neophobic |
- Summary
- TAS2R38 gene variations influence the tendency to avoid unfamiliar foods, particularly those with bitter flavors.
- Scientific insights
- Individuals with 'CC' may be more hesitant to try unfamiliar or novel foods.
- Lifestyle tips
- Gradual exposure to new foods can help reduce food neophobia.
