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 1,544 Sub-Saharan African ancestry individuals.
The effect Each copy of the A allele shifted the measure 3.72 higher; p = 4 × 10−26.
How common The A allele had a frequency of about 38% in the people studied.
Where it sits Chromosome 15, band 15q21.1 — in an intron of SLC12A1.

Anthropometric and cardio-metabolic trait variation and genetic associations in sub-Saharan Africa
Hansen MEB, et al. (American Journal of Human Genetics, 2026) is newly in the GWAS Catalog, with 166 associations across 21 traits — an atlas rather than a single question. The catalogue records its sample as 1,544 individuals. Of its 106 positions, 21 already have pages here — 1 on the Waist Circumference page; 1 on the Childhood Body Mass Index page; 1 on the Obesity and Body Weight page — including rs11636311 (near DUT), rs9920281 (SLC12A1), rs668316 (near LINC01491). Put together by code from the catalogue's records; for anything more, follow the link to the paper. PMID:42586059.
rs9920281 is a single position in the genome, in or near the SLC12A1 gene. Published research associates it with skin color in red band. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
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.
