What the study found

Who was studied 18,719 African ancestry, admixed American, East Asian ancestry, European ancestry, South Asian ancestry, Greater Middle Eastern cases, 2,441,938 African ancestry, admixed American, East Asian ancestry, European ancestry, South Asian ancestry, Greater Middle Eastern controls.

The effect Each copy of the C allele shifted the measure 0.116 higher (95% confidence interval 0.09-0.142); p = 3 × 10−18.

How common The C allele had a frequency of about 25% in the people studied.

Where it sits Chromosome 15, band 15q21.2 — in an intron of FAM227B.

What each result means

C/C Two copies of the version the research linked to Graves' disease. That is the strongest link of the three results. A link in a study is not a diagnosis.
C/T One copy of the version the research linked to Graves' disease. That is a smaller link than two copies.
T/T No copy of the version the research linked to Graves' disease. This is the starting point the study compared everyone against.

Questions about rs73398264

What is rs73398264?

rs73398264 is a single position in the genome, in or near the FAM227B gene. Published research associates it with graves' disease. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs73398264 linked to?

On MyGeneLog this position is linked to Graves' Disease. The research behind each link, and its sources, are set out on that condition page.

Does having rs73398264 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 rs73398264 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.
