Who was studied 135,482 East Asian ancestry individuals.
The effect
Each copy of the A allele shifted the measure 0.213 higher (95% confidence interval 0.15-0.28); p = 1 × 10−10.
How common The A allele had a frequency of about 0% in the people studied.
Where it sits Chromosome 15, band 15q15.2 — in an intron of TTBK2.
What each result means
A/ATwo copies of the version the research linked to Mean corpuscular hemoglobin concentration. That is the strongest link of the three results. A link in a study is not a diagnosis.
A/GOne copy of the version the research linked to Mean corpuscular hemoglobin concentration. That is a smaller link than two copies.
G/GNo copy of the version the research linked to Mean corpuscular hemoglobin concentration. This is the starting point the study compared everyone against.
rs549283835 is a single position in the genome, in or near the TTBK2 gene. Published research associates it with mean corpuscular hemoglobin concentration. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs549283835 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 rs549283835 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 rs549283835 come from?
GWAS Catalog, Nature genetics 2021, PMID:34594039. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
