Cutaneous melanoma or hair colour

SLC45A2 · rs26722

Stands on its own. Nothing else here links to this position yet — but the page above is the point: what the research found, what each genotype means, and where it came from, in language you can read. Links to conditions, drugs and the senses appear automatically if we write them.

What the study found

Who was studied 36,760 European ancestry cutaneous melanoma cases, 375,188 European ancestry controls, 352,662 European ancestry individuals.

The effect The reported allele is C; the catalogue records no effect size .

How common The C allele had a frequency of about 96% in the people studied.

Where it sits Chromosome 5, band 5p13.2 — a missense change in SLC45A2.

What ClinVar records

Classification Benign/Likely benign for SKIN/HAIR/EYE PIGMENTATION 5, BLACK/NONBLACK HAIR, Oculocutaneous albinism type 4, SLC45A2-related disorder; criteria provided, multiple submitters, no conflicts (2 of 4 stars, 6 submitters), last evaluated 2026-02-04. ClinVar record 4504 NM_016180.5(SLC45A2):c.814G>A (p.Glu272Lys)

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

C/C Two copies of the version the research linked to Cutaneous melanoma or hair colour. That is the strongest link of the three results. A link in a study is not a diagnosis.

C/T One copy of the version the research linked to Cutaneous melanoma or hair colour. That is a smaller link than two copies.

T/T No copy of the version the research linked to Cutaneous melanoma or hair colour. This is the starting point the study compared everyone against.

Questions about rs26722

What is rs26722?

rs26722 is a single position in the genome, in or near the SLC45A2 gene. Published research associates it with cutaneous melanoma or hair colour. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs26722 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 rs26722 come from?

GWAS Catalog, Nature genetics 2020, PMID:32341527. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
