rs1042602
TYRrs1042602 is a single-nucleotide polymorphism (SNP) in the TYR gene. Genespiral reads it in the Appearance analysis to describe Hair Color.

An rsID such as rs1042602 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, CA, AA. The order of the two letters carries no meaning, so CA 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 melanin production, influencing hair color from red to dark shades.
| Genotype | Association |
|---|---|
| CC | Red Hair |
| CA | Blonde/Brown Hair |
| AA | Dark Hair |
- Summary
- TYR gene variations impact hair pigmentation, particularly red or dark tones.
- Scientific insights
- 'CC' genotype is strongly associated with red hair, while 'AA' is linked to darker shades.
- Lifestyle tips
- Hair color may darken slightly with age or sun exposure.
