Age at first birth

ESR1 · rs2347867

What the study found

Who was studied 189,656 European ancestry women.

The effect Each copy of the A allele shifted the measure 0.097 higher; p = 2 × 10−9.

How common The A allele had a frequency of about 65% in the people studied.

Where it sits Chromosome 6, band 6q25.1 — in an intron of ESR1.

What each result means

A/A Two copies of the version the research linked to Age at first birth. 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 Age at first birth. That is a smaller link than two copies.
G/G No copy of the version the research linked to Age at first birth. This is the starting point the study compared everyone against.

Questions about rs2347867

What is rs2347867?

rs2347867 is a single position in the genome, in or near the ESR1 gene. Published research associates it with age at first birth. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs2347867 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 rs2347867 come from?

GWAS Catalog, Nat Genet 2016, PMID:27798627. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
