General cognitive ability

DCC · rs9966005

What the study found

Who was studied up to 300,486 European ancestry individuals.

The effect Each copy of the A allele shifted the measure 5.51 z-score higher; p = 4 × 10−8.

Where it sits Chromosome 18, band 18q21.2 — in an intron of DCC.

What each result means

A/A Two copies of the version the research linked to General cognitive ability. That is the strongest link of the three results. A link in a study is not a diagnosis.
A/G One copy of the version the research linked to General cognitive ability. That is a smaller link than two copies.
G/G No copy of the version the research linked to General cognitive ability. This is the starting point the study compared everyone against.

Questions about rs9966005

What is rs9966005?

rs9966005 is a single position in the genome, in or near the DCC gene. Published research associates it with general cognitive ability. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs9966005 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 rs9966005 come from?

GWAS Catalog, Nature communications 2018, PMID:29844566. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
