What the study found

Who was studied 21,816 African ancestry, admixed American, East Asian ancestry, European ancestry, South Asian ancestry, Greater Middle Eastern cases, 2,895,812 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 0.122 higher (95% confidence interval 0.091-0.154); p = 1 × 10−14.

How common The C allele had a frequency of about 16% in the people studied.

Where it sits Chromosome 14, band 14q22.2 — in an intron of SAMD4A-AS1.

What each result means

C/C Two 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.
C/T One copy of the version the research linked to Thyroid cancer. That is a smaller link than two copies.
T/T No copy of the version the research linked to Thyroid cancer. This is the starting point the study compared everyone against.

Questions about rs34393407

What is rs34393407?

rs34393407 is a single position in the genome, in or near the SAMD4A 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 rs34393407 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 rs34393407 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 rs34393407 come from?

GWAS Catalog, GWAS Catalog n.d., PMID:41644669. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
