Complement C4 levels (C4A.C4B.4481.34.2)

near HLA-DRB6 · rs116180191

What the study found

Who was studied 3,301 European ancestry individuals.

The effect Each copy of the A allele shifted the measure 0.19 lower (95% confidence interval -0.13--0.25); p = 3 × 10−12.

How common The A allele had a frequency of about 37% in the people studied.

Where it sits Chromosome 6, band 6p21.32 — between genes, 8.6 kb from HLA-DRB6.

What each result means

A/A Two copies of the version the research linked to Complement C4 levels (C4A.C4B.4481.34.2). That is the strongest link of the three results. A link in a study is not a diagnosis.
A/T One copy of the version the research linked to Complement C4 levels (C4A.C4B.4481.34.2). That is a smaller link than two copies.
T/T No copy of the version the research linked to Complement C4 levels (C4A.C4B.4481.34.2). This is the starting point the study compared everyone against.

Questions about rs116180191

What is rs116180191?

rs116180191 is a single position in the genome, in or near the near HLA-DRB6 gene. Published research associates it with complement c4 levels (c4a.c4b.4481.34.2). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs116180191 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 rs116180191 come from?

GWAS Catalog, Nature 2018, PMID:29875488. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
