Stands on its own.

research found, what each genotype means, and where it came from, in language you can

What the study found
Who was studied 13,226 European ancestry early onset individuals, 161,175 European ancestry average onset individuals.
The effect
Each copy of the G allele shifted the measure 0.0185 years lower (95% confidence interval 0.015-0.022); p = 8 × 10−31.
Where it sits Chromosome 15, band 15q13.1 — in an intron of HERC2.
What each result means
A/ANo copy of the version the research linked to Male puberty timing (early vs. average onset facial hair). This is the starting point the study compared everyone against.
A/GOne copy of the version the research linked to Male puberty timing (early vs. average onset facial hair). That is a smaller link than two copies.
G/GTwo copies of the version the research linked to Male puberty timing (early vs. average onset facial hair). That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs7402990
What is rs7402990?
rs7402990 is a single position in the genome, in or near the HERC2 gene. Published research associates it with male puberty timing (early vs. average onset facial hair). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
Does having rs7402990 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 rs7402990 come from?
GWAS Catalog, Nature communications 2020, PMID:32210231. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
