Straight vs curly hair

EDAR · rs260643

What the study found

Who was studied 2,532 Japanese ancestry female straight hair individuals, 2,346 Japanese ancestry female curly hair individuals.

The effect Each copy of the A allele carried 3.33 times the odds of Straight vs curly hair (95% confidence interval 3.03-3.7); p = 2 × 10−103.

How common The A allele had a frequency of about 80% in the people studied.

Where it sits Chromosome 2, band 2q13 — in an intron of RANBP2.

What ClinVar records

Classification Benign; criteria provided, multiple submitters, no conflicts (2 of 4 stars, 2 submitters), last evaluated 2018-11-11. ClinVar record 1183466 NM_022336.4(EDAR):c.442+171T>C

What this is ClinVar's aggregate record for this position (as of its 2026-10-12 release), not a result about you. A classification describes the variant against the condition named, as laboratories submitted it. Whether a person carries this variant, and what that would mean for them, is a question for a clinical test and a genetic counsellor.

What each result means

A/A Two copies of the version the research linked to Straight vs curly hair. That is the strongest link of the three results. A link in a study is not a diagnosis.
A/G One copy of the version the research linked to Straight vs curly hair. That is a smaller link than two copies.
G/G No copy of the version the research linked to Straight vs curly hair. This is the starting point the study compared everyone against.

Questions about rs260643

What is rs260643?

rs260643 is a single position in the genome, in or near the EDAR gene. Published research associates it with straight vs curly hair. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs260643 mean I will get this?

No. Common variants like this one move a probability slightly and, on their own, rarely decide anything about one person. Nothing on this page is a diagnosis, and health decisions should be made with a clinician who can see your whole picture.

Where does the information about rs260643 come from?

GWAS Catalog, Sci Rep 2018, PMID:29895819. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
