Where this position leads

What the study found

Who was studied 31,197 European ancestry cases, 61,770 European ancestry controls.

The effect Each copy of the A allele carried 1.08 times the odds of Colorectal cancer (95% confidence interval 1.05-1.10); p = 1 × 10⁻⁸.

How common The A allele had a frequency of about 73% in the people studied.

Where it sits Chromosome 15, band 15q22.31 — in an intron of SMAD6.

What each result means

A/A Two copies of the version the research linked to Colorectal cancer. That is the strongest link of the three results. A link in a study is not a diagnosis.

A/G One copy of the version the research linked to Colorectal cancer. That is a smaller link than two copies.

G/G No copy of the version the research linked to Colorectal cancer. This is the starting point the study compared everyone against.

Questions about rs4776316

What is rs4776316?

rs4776316 is a single position in the genome, in or near the SMAD6 gene. Published research associates it with colorectal 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 rs4776316 linked to?

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

Does having rs4776316 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 rs4776316 come from?

GWAS Catalog, Nat Commun 2019, PMID:31089142. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
