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 38,200 European ancestry individuals.
The effect
Each copy of the A allele shifted the measure 0.085 SD units higher (95% confidence interval 0.065-0.105); p = 8 × 10−17.
How common The A allele had a frequency of about 21% in the people studied.
Where it sits Chromosome 2, band 2q13 — in an intron of MIR4435-2HG.
What each result means
A/ATwo copies of the version the research linked to Red blood cell haemoglobin equivalent. That is the strongest link of the three results. A link in a study is not a diagnosis.
A/GOne copy of the version the research linked to Red blood cell haemoglobin equivalent. That is a smaller link than two copies.
G/GNo copy of the version the research linked to Red blood cell haemoglobin equivalent. This is the starting point the study compared everyone against.

Questions about rs138039400
What is rs138039400?
rs138039400 is a single position in the genome, in or near the MIR4435-2HG gene. Published research associates it with red blood cell haemoglobin equivalent. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
Does having rs138039400 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 rs138039400 come from?
GWAS Catalog, Nature communications 2023, PMID:37596262. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
