DCC · rs62083414

Strength of the evidence

1 / 4

Its strongest genetic-study result is p = 10−8, with 1 associations in the GWAS Catalog.

How this is scored

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 53,688 Finnish ancestry cases, 228,060 Finnish ancestry controls.

The effect Each copy of the C allele shifted the measure 0.046 lower; p = 5 × 10−9.

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

What each result means

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

Questions about rs62083414

What is rs62083414?

rs62083414 is a single position in the genome, in or near the DCC gene. Published research associates it with blood donation. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs62083414 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 rs62083414 come from?

GWAS Catalog, European journal of human genetics : EJHG 2026, PMID:42045633. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
