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 562,259 European ancestry individuals.

The effect Each copy of the T allele shifted the measure 0.0129 SD unit higher (95% confidence interval 0.0091-0.0168); p = 3 × 10⁻¹¹.

How common The T allele had a frequency of about 34% in the people studied.

Where it sits Chromosome 1, band 1q21.3 — in an intron of TDRKH.

What each result means

C/C No copy of the version the research linked to Hematocrit. This is the starting point the study compared everyone against.

C/T One copy of the version the research linked to Hematocrit. That is a smaller link than two copies.

T/T Two copies of the version the research linked to Hematocrit. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs868868

What is rs868868?

rs868868 is a single position in the genome, in or near the TDRKH gene. Published research associates it with hematocrit. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs868868 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 rs868868 come from?

GWAS Catalog, Cell 2020, PMID:32888493. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
