What is gene testing
... Predictive gene tests look for disorders that "run in families" as the result of a faulty gene that is inherited. Sometimes a mother’s egg or a father’s sperm may have a mutation, or error, in a gene. When the egg and sperm make a new individual, all of that individual’s DNA will have the error. Doc ...
