The Claim

The presence of colibactin mutation signatures in colorectal cancer is not associated with differences in tumor mutational burden or known driver mutations, indicating that colibactin contributes to cancer development through a distinct genomic pathway.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

Colorectal cancers with colibactin-related DNA damage patterns show the same levels of overall mutations and known cancer-causing gene changes as other colorectal cancers, suggesting colibactin causes cancer through a different biological mechanism.

What the research says

1 study

  1. Study: Abstract 2796: Colibactin mutation signatures are associated with younger age of onset in colorectal cancer

    This study found that a specific bacterial toxin (colibactin) causes a unique pattern of DNA damage in colon cancer, but doesn’t change the overall number of mutations or known cancer-causing genes—meaning it makes cancer grow in its own special way, different from other causes.
