Testosterone levels

AR · rs147181229

What the study found

Who was studied 243,951 European and South Asian ancestry males.

The effect Each copy of the A allele shifted the measure 0.06 lower (95% confidence interval 0.053-0.067); p = 4 × 10−57.

How common The A allele had a frequency of about 8% in the people studied.

Where it sits Chromosome X, band Xq12 — in an intron of AR.

What each result means

A/A 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.
A/G One copy of the version the research linked to Testosterone levels. That is a smaller link than two copies.
G/G No copy of the version the research linked to Testosterone levels. This is the starting point the study compared everyone against.

Questions about rs147181229

What is rs147181229?

rs147181229 is a single position in the genome, in or near the AR 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 rs147181229 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 rs147181229 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.
