Family members affected by genetic health problems are tied together by the legacy of their shared inheritance. Genetic health problems can be predicted in families when there is a confirmed family history of an inherited disorder and/or through a predictive genetic test. Predictions are presented as risks or probabilities that family members could develop future health problems.

This entry describes predictive genetic testing and associated ethical issues within a family context. It is important to understand family context in genetic prediction in order to maximize family functioning and provide appropriate professional services.
