Where this position leads

What the study found

Who was studied 370,711 European ancestry individuals.

The effect Each copy of the T allele shifted the measure 0.0155 lower (95% confidence interval 0.01-0.021); p = 2 × 10⁻⁹.

How common The T allele had a frequency of about 30% in the people studied.

Where it sits Chromosome 12, band 12q24.23 — in an intron of CIT.

What ClinVar records

Classification Benign; criteria provided, multiple submitters, no conflicts (2 of 4 stars, 2 submitters), last evaluated 2018-07-17. ClinVar record 1256930 NM_001206999.2(CIT):c.4685-44G>A

What this is ClinVar's aggregate record for this position (as of its 2026-10-05 release), not a result about you. A classification describes the variant against the condition named, as laboratories submitted it. Whether a person carries this variant, and what that would mean for them, is a question for a clinical test and a genetic counsellor.

What each result means

C/C Published research associates this genotype with typical/baseline likelihood of Number of sexual partners — 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 Number of sexual partners.

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

Questions about rs804667

What is rs804667?

rs804667 is a single position in the genome, in or near the CIT gene. Published research associates it with number of sexual partners. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs804667 linked to?

On MyGeneLog this position is linked to Adventurousness. The research behind each link, and its sources, are set out on that condition page.

Does having rs804667 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 rs804667 come from?

GWAS Catalog, Nat Genet 2019, PMID:30643258. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
