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 3,506 European ancestry individuals.
The effect
Each copy of the T allele shifted the measure 0.322 higher (95% confidence interval 0.25-0.4); p = 2 × 10−17.
How common The T allele had a frequency of about 10% in the people studied.
Where it sits Chromosome 6, band 6p21.33 — between genes, 1.5 kb from HCG20.
What each result means
C/CNo copy of the version the research linked to Butyrophilin subfamily 2 member A1 levels. This is the starting point the study compared everyone against.
C/TOne copy of the version the research linked to Butyrophilin subfamily 2 member A1 levels. That is a smaller link than two copies.
T/TTwo copies of the version the research linked to Butyrophilin subfamily 2 member A1 levels. That is the strongest link of the three results. A link in a study is not a diagnosis.
rs3129984 is a single position in the genome, in or near the near HCG20 gene. Published research associates it with butyrophilin subfamily 2 member a1 levels. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
Does having rs3129984 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 rs3129984 come from?
GWAS Catalog, Nature genetics 2024, PMID:39528825. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
