near SLC45A2 · rs35404

What the study found

Who was studied 4,985 Iberian ancestry individuals.

The effect Each copy of the G allele shifted the measure 0.619 lower (95% confidence interval 0.48-0.76); p = 6 × 10−19.

How common The G allele had a frequency of about 2% in the people studied.

Where it sits Chromosome 5, band 5p13.2 — between genes, 0.2 kb from SLC45A2.

What ClinVar records

Classification Benign; criteria provided, single submitter (1 of 4 stars, 1 submitter), last evaluated 2018-11-12. ClinVar record 1263925 NC_000005.10:g.33944407A>G

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

Questions about rs35404

What is rs35404?

rs35404 is a single position in the genome, in or near the near SLC45A2 gene. Published research associates it with skin color. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs35404 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 rs35404 come from?

GWAS Catalog, Genes 2023, PMID:36672889. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
