Where this position leads

What the study found

Who was studied 721,201 African American or Afro-Caribbean, African ancestry, European ancestry, East Asian ancestry, Hispanic or Latin American and South Asian ancestry individuals.

The effect The reported allele is C; the catalogue records no effect size ; p = 2 × 10⁻³⁰.

How common The C allele had a frequency of about 21% in the people studied.

Where it sits Chromosome 22, band 22q12.2 — between genes, 1.8 kb from CASTOR1.

What each result means

C/C Two copies of the version the research linked to Platelet count. 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 Platelet count. That is a smaller link than two copies.

T/T No copy of the version the research linked to Platelet count. This is the starting point the study compared everyone against.

Questions about rs56300819

What is rs56300819?

rs56300819 is a single position in the genome, in or near the near CASTOR1 gene. Published research associates it with platelet count. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs56300819 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 rs56300819 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 rs56300819 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.
