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 230,454 European ancestry women.
The effect
Each copy of the C allele shifted the measure 0.026 higher (95% confidence interval 0.019-0.033); p = 2 × 10−13.
How common The C allele had a frequency of about 18% in the people studied.
Where it sits Chromosome 21, band 21q21.1 — between genes, 203 kb from RNU1-98P.
What each result means
C/CTwo copies of the version the research linked to Total testosterone levels. That is the strongest link of the three results. A link in a study is not a diagnosis.
C/TOne copy of the version the research linked to Total testosterone levels. That is a smaller link than two copies.
T/TNo copy of the version the research linked to Total testosterone levels. This is the starting point the study compared everyone against.

Questions about rs2824138
What is rs2824138?
rs2824138 is a single position in the genome, in or near the near RNU1-98P gene. Published research associates it with total testosterone levels. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
Does having rs2824138 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 rs2824138 come from?
GWAS Catalog, Nature medicine 2020, PMID:32042192. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
