Who was studied Up to 182,413 European ancestry females.
The effect
Each copy of the C allele shifted the measure 0.04 higher (95% confidence interval 0.03-0.05); p = 5 × 10−11.
How common The C allele had a frequency of about 30% in the people studied.
Where it sits Chromosome 18, band 18p11.31 — in an intron of DLGAP1.
What each result means
C/CTwo 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.
C/TOne copy of the version the research linked to Menarche (age at onset). That is a smaller link than two copies.
T/TNo copy of the version the research linked to Menarche (age at onset). This is the starting point the study compared everyone against.
rs12607903 is a single position in the genome, in or near the DLGAP1 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 rs12607903 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 rs12607903 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 rs12607903 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.
