What the study found

Who was studied 460,935 European ancestry individuals.

The effect Each copy of the C allele shifted the measure 0.0145 SD unit higher (95% confidence interval 0.011-0.018); p = 6 × 10−14.

How common The C allele had a frequency of about 57% in the people studied.

Where it sits Chromosome 1, band 1q42.3 — in an intron of NID1.

What ClinVar records

Classification Benign; criteria provided, single submitter (1 of 4 stars, 1 submitter), last evaluated 2018-11-12. ClinVar record 1271670 NM_002508.3(NID1):c.753-112G>A

What this is ClinVar's aggregate record for this position (as of its 2026-10-19 release), not a result about you. A classification describes the variant against the condition named, as laboratories submitted it. Whether a person carries this variant, and what that would mean for them, is a question for a clinical test and a genetic counsellor.

What each result means

C/C Two copies of the version the research linked to Mean platelet volume. 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 Mean platelet volume. That is a smaller link than two copies.
T/T No copy of the version the research linked to Mean platelet volume. This is the starting point the study compared everyone against.

Questions about rs12033187

What is rs12033187?

rs12033187 is a single position in the genome, in or near the NID1 gene. Published research associates it with mean platelet volume. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs12033187 linked to?

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

Does having rs12033187 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 rs12033187 come from?

GWAS Catalog, Cell 2020, PMID:32888493. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
