The effect
Each copy of the A allele shifted the measure 0.0203 higher (95% confidence interval 0.014-0.026); p = 1 × 10−10.
How common The A allele had a frequency of about 41% in the people studied.
Where it sits Chromosome 3, band 3p26.1 — in an intron of ITPR1.
What each result means
A/ATwo copies of the version the research linked to Male-pattern baldness. That is the strongest link of the three results. A link in a study is not a diagnosis.
A/GOne copy of the version the research linked to Male-pattern baldness. That is a smaller link than two copies.
G/GNo copy of the version the research linked to Male-pattern baldness. This is the starting point the study compared everyone against.

Questions about rs13313995
What is rs13313995?
rs13313995 is a single position in the genome, in or near the ITPR1 gene. Published research associates it with male-pattern baldness. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs13313995 linked to?
On MyGeneLog this position is linked to Androgenetic Alopecia (Male Pattern Baldness). The research behind each link, and its sources, are set out on that condition page.
Does having rs13313995 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 rs13313995 come from?
GWAS Catalog, Nat Commun 2018, PMID:30573740. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
