As a demonstration of the utility of the tool, we posed the following question: “How different are mutation frequencies in the MLH1 gene from colorectal cancer cases with a family history of pancreatic cancer versus the family history of prostate cancers?” To answer this question, the data were filtered for individuals with “First Cancer” as “Colorectal”, and then selecting either “Prostate” or “Pancreatic” in the box labeled “What cancers are in the family?”. This evidence concerns the gene MLH1 and colorectal cancer.
