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 178,782 European ancestry men.
The effect
Each copy of the G allele shifted the measure 0.0526 higher (95% confidence interval 0.047-0.058); p = 9 × 10−90.
How common The G allele had a frequency of about 20% in the people studied.
Where it sits Chromosome X, band Xp11.21 — in an intron of NBDY.
What each result means
C/CNo copy of the version the research linked to Bioavailable testosterone levels. This is the starting point the study compared everyone against.
C/GOne copy of the version the research linked to Bioavailable testosterone levels. That is a smaller link than two copies.
G/GTwo copies of the version the research linked to Bioavailable testosterone levels. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs5913997
What is rs5913997?
rs5913997 is a single position in the genome, in or near the NBDY gene. Published research associates it with bioavailable 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 rs5913997 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 rs5913997 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.
