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 194,453 European ancestry men.

The effect Each copy of the T allele shifted the measure 0.133 higher (95% confidence interval 0.091-0.174); p = 8 × 10⁻¹¹.

How common The T allele had a frequency of about 1% in the people studied.

Where it sits Chromosome 14, band 14q32.13 — between genes, 4.9 kb from SERPINA1.

What each result means

C/C Published research associates this genotype with typical/baseline likelihood of Total testosterone levels — no copies of the reported risk allele.

C/T Published research associates this genotype (one copy of the reported risk allele) with an intermediate association with Total testosterone levels.

T/T Published research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Total testosterone levels compared to the general population.

Questions about rs145602600

What is rs145602600?

rs145602600 is a single position in the genome, in or near the near SERPINA1 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 rs145602600 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 rs145602600 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.
