What the study found

Who was studied 299,017 European ancestry individuals.

The effect Each copy of the G allele shifted the measure 0.017 higher (95% confidence interval 0.011-0.023); p = 8 × 10−9.

How common The G allele had a frequency of about 61% in the people studied.

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

What each result means

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

Questions about rs4462678

What is rs4462678?

rs4462678 is a single position in the genome, in or near the DCC gene. Published research associates it with attention deficit hyperactivity disorder. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs4462678 linked to?

On MyGeneLog this position is linked to ADHD (Attention Deficit Hyperactivity Disorder). The research behind each link, and its sources, are set out on that condition page.

Does having rs4462678 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 rs4462678 come from?

GWAS Catalog, Nature genetics 2025, PMID:40962958. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
