What each result means

A/A Published research associates this genotype with typical/baseline likelihood of Mean corpuscular volume — no copies of the reported risk allele.
A/G Published research associates this genotype (one copy of the reported risk allele) with an intermediate association with Mean corpuscular volume.
G/G Published research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Mean corpuscular volume compared to the general population.

Questions about rs7786877

What is rs7786877?

rs7786877 is a single position in the genome, in or near the TFR2 gene. Published research associates it with mean corpuscular volume. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs7786877 linked to?

On MyGeneLog this position is linked to Blood Cell Counts. The research behind each link, and its sources, are set out on that condition page.

Does having rs7786877 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 rs7786877 come from?

GWAS Catalog, Nat Genet 2009, PMID:19862010. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
