What the study found

Who was studied 205,327 European ancestry males.

The effect Each copy of the A allele shifted the measure 0.033 higher (95% confidence interval 0.023-0.043); p = 5 × 10−10.

How common The A allele had a frequency of about 10% in the people studied.

Where it sits Chromosome 13, band 13q34 — in an intron of COL4A2.

What each result means

A/A Two 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/G One copy of the version the research linked to Male-pattern baldness. That is a smaller link than two copies.
G/G No copy of the version the research linked to Male-pattern baldness. This is the starting point the study compared everyone against.

Questions about rs9559793

What is rs9559793?

rs9559793 is a single position in the genome, in or near the COL4A2 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 rs9559793 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 rs9559793 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 rs9559793 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.
