Stands on its own.
Nothing else here links to this position yet — but the page above is the point: what the
research found, what each genotype means, and where it came from, in language you can
read. Links to conditions, drugs and the senses appear automatically if we write them.
What the study found
Who was studied 66,797 Chinese ancestry individuals; replicated in 36,982 Chinese ancestry individuals.
The effect
Each copy of the C allele shifted the measure 0.132 lower (95% confidence interval 0.11-0.15); p = 4 × 10−49.
How common The C allele had a frequency of about 26% in the people studied.
Where it sits Chromosome 4, band 4q25 — between genes, 13.1 kb from EGF.
What each result means
C/CTwo copies of the version the research linked to Platelet count in second trimester. That is the strongest link of the three results. A link in a study is not a diagnosis.
C/GOne copy of the version the research linked to Platelet count in second trimester. That is a smaller link than two copies.
G/GNo copy of the version the research linked to Platelet count in second trimester. This is the starting point the study compared everyone against.
rs77001541 is a single position in the genome, in or near the near EGF gene. Published research associates it with platelet count in second trimester. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
Does having rs77001541 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 rs77001541 come from?
GWAS Catalog, Nature genetics 2026, PMID:42509370. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
