What information found in a family health tree indicates that a disease might have a genetic link?

Understanding how genetics play a role in the development of certain diseases is an important aspect of understanding one’s personal health. If you are considering having your DNA tested, it might be worth looking into family medical history to see if there is any information that may indicate some genetic links for disease genes. Your doctor or a specialist can help you determine what type of tests will provide the best data about your own health and susceptibility to developing certain conditions based on their knowledge base and expertise.
