What the study found

Who was studied 172,332 European ancestry individuals.

The effect Each copy of the T allele shifted the measure 0.057 higher (95% confidence interval 0.042-0.072); p = 2 × 10−14.

How common The T allele had a frequency of about 6% in the people studied.

Where it sits Chromosome 14, band 14q32.32 — between genes, 4.9 kb from MARK3.

What each result means

C/C Published research associates this genotype with typical/baseline likelihood of Mean corpuscular hemoglobin — no copies of the reported risk allele.
C/T Published research associates this genotype (one copy of the reported risk allele) with an intermediate association with Mean corpuscular hemoglobin.
T/T Published research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Mean corpuscular hemoglobin compared to the general population.

Questions about rs77697190

What is rs77697190?

rs77697190 is a single position in the genome, in or near the MARK3 gene. Published research associates it with mean corpuscular hemoglobin. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs77697190 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 rs77697190 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 rs77697190 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.
