What is a germline mutation?
A mutation from the egg or sperm that is found in all cells of your body (myRisk testing) these are inherited.
What is a somatic mutation?
mutation that first occurred in a particular cell (tumors) These are genetic changes that are acquired (environmental like UV or Chemical exposure) and are not inherited. They are not found in all cells of the body.
