Questions about rs3774749

What is rs3774749?

rs3774749 is a single position in the genome, in or near the SEMA3F gene. Published research associates it with intelligence (mtag). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs3774749 linked to?

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

Does having rs3774749 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 rs3774749 come from?

GWAS Catalog, Mol Psychiatry 2018, PMID:29326435. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
