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 626 African American or Afro-Caribbean cases, 119,956 African American or Afro-Caribbean controls, 2,389 European ancestry cases, 444,228 European ancestry controls, 393 Hispanic or Latin American cases, 58,720 Hispanic or Latin American controls.
The effect
Each copy of the T allele shifted the measure 2.22 lower (95% confidence interval 2.17-2.27); p = 1 × 10−13.
How common The T allele had a frequency of about 100% in the people studied.
Where it sits Chromosome 1, band 1p36.23 — in an intron of PER3.
What each result means
A/ANo copy of the version the research linked to Decreased libido (PheCode 302.1). This is the starting point the study compared everyone against.
A/TOne copy of the version the research linked to Decreased libido (PheCode 302.1). That is a smaller link than two copies.
T/TTwo copies of the version the research linked to Decreased libido (PheCode 302.1). That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs189355347
What is rs189355347?
rs189355347 is a single position in the genome, in or near the PER3 gene. Published research associates it with decreased libido (phecode 302.1). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
Does having rs189355347 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 rs189355347 come from?
GWAS Catalog, Science (New York, N.Y.) 2024, PMID:39024449. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
