Testosterone levels

SLC25A37 · rs10866828

What the study found

Who was studied 235,579 European ancestry females.

The effect Each copy of the T allele shifted the measure 0.0247 higher (95% confidence interval 0.018-0.031); p = 3 × 10−13.

How common The T allele had a frequency of about 26% in the people studied.

Where it sits Chromosome 8, band 8p21.2 — in an intron of SLC25A37.

What each result means

C/C No copy of the version the research linked to Testosterone levels. This is the starting point the study compared everyone against.
C/T One copy of the version the research linked to Testosterone levels. That is a smaller link than two copies.
T/T Two copies of the version the research linked to Testosterone levels. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs10866828

What is rs10866828?

rs10866828 is a single position in the genome, in or near the SLC25A37 gene. Published research associates it with 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 rs10866828 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 rs10866828 come from?

GWAS Catalog, Nature genetics 2025, PMID:40229599. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
