Who was studied 172,433 European ancestry individuals.
The effect
Each copy of the T allele shifted the measure 0.0607 higher (95% confidence interval 0.046-0.075); p = 2 × 10−16.
How common The T allele had a frequency of about 6% in the people studied.
Where it sits Chromosome 16, band 16q22.1 — in an intron of MATCAP1.
What each result means
C/CNo copy of the version the research linked to Mean corpuscular volume. This is the starting point the study compared everyone against.
C/TOne copy of the version the research linked to Mean corpuscular volume. That is a smaller link than two copies.
T/TTwo copies of the version the research linked to Mean corpuscular volume. That is the strongest link of the three results. A link in a study is not a diagnosis.
rs13339140 is a single position in the genome, in or near the KIAA0895L gene. Published research associates it with mean corpuscular volume. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs13339140 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 rs13339140 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 rs13339140 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.
