Who was studied 14,764 European ancestry cases, 2,091,602 European ancestry controls.
The effect
Each copy of the T allele shifted the measure 0.131 higher (95% confidence interval 0.1-0.16); p = 1 × 10−17.
How common The T allele had a frequency of about 75% in the people studied.
Where it sits Chromosome 19, band 19p13.2 — in an intron of INSR.
What each result means
G/GNo copy of the version the research linked to Thyroid cancer. This is the starting point the study compared everyone against.
G/TOne copy of the version the research linked to Thyroid cancer. That is a smaller link than two copies.
T/TTwo copies of the version the research linked to Thyroid cancer. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs4804433
What is rs4804433?
rs4804433 is a single position in the genome, in or near the INSR gene. Published research associates it with thyroid cancer. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs4804433 linked to?
On MyGeneLog this position is linked to Thyroid Cancer. The research behind each link, and its sources, are set out on that condition page.
Does having rs4804433 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 rs4804433 come from?
GWAS Catalog, Nature genetics 2026, PMID:41644669. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
