An rsID such as rs12821256 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 GG, GT, TT. The order of the two letters carries no meaning, so GT 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.
Hair Color
Appearance · Part of the Appearance analysis
Involved in pigmentation, contributing to variations in hair color.
| Genotype | Association |
|---|---|
| GG | Lighter Hair |
| GT | Intermediate Hair Color |
| TT | Darker Hair |
- Summary
- KITLG gene variations can result in different hair shades, from light to dark.
- Scientific insights
- 'GG' alleles are often associated with lighter hair shades.
- Lifestyle tips
- Natural hair color can darken slightly with age or sun exposure.
