C7 · rs2271708

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 2,935 Qatari ancestry individuals.

The effect Each copy of the C allele shifted the measure 1.32 lower (95% confidence interval 1.08-1.57); p = 7 × 10⁻²⁷.

How common The C allele had a frequency of about 1% in the people studied.

Where it sits Chromosome 5, band 5p13.1 — a missense change in C7.

What each result means

C/C Published research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Complement component C7 levels compared to the general population.

C/T Published research associates this genotype (one copy of the reported risk allele) with an intermediate association with Complement component C7 levels.

T/T Published research associates this genotype with typical/baseline likelihood of Complement component C7 levels — no copies of the reported risk allele.

Questions about rs2271708

What is rs2271708?

rs2271708 is a single position in the genome, in or near the C7 gene. Published research associates it with complement component c7 levels. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs2271708 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 rs2271708 come from?

GWAS Catalog, Human molecular genetics 2023, PMID:36168886. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
