The effect
Each copy of the C allele shifted the measure 0.0391 higher (95% confidence interval 0.028-0.05); p = 1 × 10−12.
How common The C allele had a frequency of about 9% in the people studied.
Where it sits Chromosome 16, band 16q23.2 — between genes, 35.7 kb from CMC2.
What each result means
C/CTwo 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.
C/TOne copy of the version the research linked to Male-pattern baldness. That is a smaller link than two copies.
T/TNo copy of the version the research linked to Male-pattern baldness. This is the starting point the study compared everyone against.

Questions about rs139157021
What is rs139157021?
rs139157021 is a single position in the genome, in or near the near CMC2 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 rs139157021 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 rs139157021 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 rs139157021 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.
