DCC · rs11663393
Where this position leads
Condition: Depression (Self-Reported Symptoms)
Strength of the evidence
Its strongest genetic-study result is p = 10−10, with 4 associations in the GWAS Catalog.
4: ClinVar disease-causing, reviewed by an expert panel or a guideline (3–4 stars). 3: ClinVar, several labs agreeing (2 stars), or a genetic study at p ≤ 10−50. 2: ClinVar from one lab (1 star), or p ≤ 10−20. 1: ClinVar submitted without criteria (0 stars), or genome-wide significance (p ≤ 5×10−8). The higher of the two counts. It says how solid the evidence is, not whether it matters for a particular person.
What the study found
Who was studied 354,862 European ancestry individuals.
The effect Each copy of the G allele shifted the measure 0.0139 lower (95% confidence interval 0.0092-0.0186); p = 6 × 10−9.
How common The G allele had a frequency of about 55% in the people studied.
Where it sits Chromosome 18, band 18q21.2 — in an intron of DCC.

rs11663393 is a single position in the genome, in or near the DCC gene. Published research associates it with depressive symptoms. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
On MyGeneLog this position is linked to Depression (Self-Reported Symptoms). The research behind each link, and its sources, are set out on that condition page.
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.
