research found, what each genotype means, and where it came from, in language you can
read. Links to conditions, drugs and the senses appear automatically if we write them.
What the study found
Who was studied 746,431 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 A; the catalogue records no effect size
; p = 3 × 10−10.
How common The A allele had a frequency of about 41% in the people studied.
Where it sits Chromosome 7, band 7p22.3 — in an intron of GNA12.
What each result means
A/A
Published research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Hemoglobin concentration compared to the general population.
A/G
Published research associates this genotype (one copy of the reported risk allele) with an intermediate association with Hemoglobin concentration.
G/G
Published research associates this genotype with typical/baseline likelihood of Hemoglobin concentration — no copies of the reported risk allele.

Questions about rs798503
What is rs798503?
rs798503 is a single position in the genome, in or near the GNA12 gene. Published research associates it with hemoglobin concentration. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
Does having rs798503 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 rs798503 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.
