rs17646946
TCHHrs17646946 is a single-nucleotide polymorphism (SNP) in the TCHH gene. Genespiral reads it in the Appearance analysis to describe Hair Curliness.

An rsID such as rs17646946 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, GA, AA. The order of the two letters carries no meaning, so GA 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 Curliness
Appearance · Part of the Appearance analysis
Affects the shape of hair follicles, influencing curliness.
| Genotype | Association |
|---|---|
| GG | Straight Hair |
| GA | Wavy Hair |
| AG | Wavy Hair |

- Summary
- Variations contribute to the texture and curl pattern of hair.
- Scientific insights
- The 'AA' genotype is associated with curly hair, while 'GG' correlates with straight hair.
- Lifestyle tips
- Use hair care products designed for your hair type to enhance natural texture.
