Genes are the instructions a person s body uses to function. Genome sequencing is a new way to look at genes that your main research team is using to learn the causes of the condition they are studying. When a new cause is found this way, it is called a primary variant. Each person has many variants. Most do not cause disease. Sequencing can also find secondary variants. These are not related to the condition your main research team is studying, but may show a person to be at high risk for cancer or another condition. Researchers want to learn more about what it means to have a secondary variant.
