Who was studied 172,851 European ancestry individuals.
The effect
Each copy of the C allele shifted the measure 0.0462 lower (95% confidence interval 0.039-0.053); p = 9 × 10−40.
How common The C allele had a frequency of about 43% in the people studied.
Where it sits Chromosome 22, band 22q12.3 — in a non-coding transcript of TMPRSS6.
What each result means
C/CPublished research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Mean corpuscular hemoglobin concentration compared to the general population.
C/TPublished research associates this genotype (one copy of the reported risk allele) with an intermediate association with Mean corpuscular hemoglobin concentration.
T/TPublished research associates this genotype with typical/baseline likelihood of Mean corpuscular hemoglobin concentration — no copies of the reported risk allele.
rs228918 is a single position in the genome, in or near the TMPRSS6 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 rs228918 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 rs228918 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 rs228918 come from?
GWAS Catalog, Cell 2016, PMID:27863252. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
