CCDC85A · rs6747380

Where this position leads

What the study found

Who was studied Up to 182,413 European ancestry females.

The effect Each copy of the A allele shifted the measure 0.07 higher (95% confidence interval 0.056-0.084); p = 6 × 10⁻²⁸.

How common The A allele had a frequency of about 17% in the people studied.

Where it sits Chromosome 2, band 2p16.1 — in an intron of CCDC85A.

What each result means

A/A Two copies of the version the research linked to Menarche (age at onset). 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 Menarche (age at onset). That is a smaller link than two copies.

G/G No copy of the version the research linked to Menarche (age at onset). This is the starting point the study compared everyone against.

Questions about rs6747380

What is rs6747380?

rs6747380 is a single position in the genome, in or near the CCDC85A gene. Published research associates it with menarche (age at onset). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs6747380 linked to?

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

Does having rs6747380 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 rs6747380 come from?

GWAS Catalog, Nature 2014, PMID:25231870. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
