Who was studied 172,433 European ancestry individuals.
The effect
Each copy of the C allele shifted the measure 0.0681 higher (95% confidence interval 0.061-0.075); p = 3 × 10−79.
How common The C allele had a frequency of about 39% in the people studied.
Where it sits Chromosome 19, band 19p13.13 — between genes, 1.4 kb from GCDH.
What each result means
C/CPublished research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Mean corpuscular volume compared to the general population.
C/GPublished research associates this genotype (one copy of the reported risk allele) with an intermediate association with Mean corpuscular volume.
G/GPublished research associates this genotype with typical/baseline likelihood of Mean corpuscular volume — no copies of the reported risk allele.
rs56397034 is a single position in the genome, in or near the GCDH 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 rs56397034 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 rs56397034 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 rs56397034 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.
