Overview

About this study

A group of Mayo Clinic Biobank participants were genotyped for genetic variants as part of a separate study and a subset were found to be carriers of one or more important variants that increased risk of severe (grade 3, 4 or 5) toxicity.   

These variants were reviewed by experts at Mayo Clinic and judged to:  1) have important health implications (toxicity) for participants if they were ever exposed to pharmaceutical agents containing 5-fluoruracil, and 2) to be clinically actionable (change options for treatment).

The purpose of this study is to return results to participants enrolled in the Mayo Clinic Biobank (IRB 08-007049) who are known to carry genetic variants likely to cause toxicity if exposed to 5FU or capecitibine.
