Where this position leads

What the study found

Who was studied 630,125 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 G; the catalogue records no effect size ; p = 9 × 10⁻³⁶.

How common The G allele had a frequency of about 7% in the people studied.

Where it sits Chromosome 7, band 7q21.2 — between genes, 38.5 kb from RN7SL7P.

What each result means

A/A Published research associates this genotype with typical/baseline likelihood of Mean corpuscular hemoglobin — no copies of the reported risk allele.

A/G Published research associates this genotype (one copy of the reported risk allele) with an intermediate association with Mean corpuscular hemoglobin.

G/G Published research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Mean corpuscular hemoglobin compared to the general population.

Questions about rs74298199

What is rs74298199?

rs74298199 is a single position in the genome, in or near the near SAMD9 gene. Published research associates it with mean corpuscular hemoglobin. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs74298199 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 rs74298199 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 rs74298199 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.
