also called a genogram or genetic pedigree
visual representation of your familys genetic history
illustrates the patterns of health and illness within a family
pinpoints areas of special concern or risk for you |

needed information: each family members: DOB, major diseases; for deceased members: cause of death and age

|
Definition
an early onset of disease is more likely to have a genetic component
The appearance of a disease in multiple individuals on the same side of the family is more like to have a genetic correlation
a family member with multiple cancers represents a greater likelihood of a genetic association
the presence of disease in family members who have good health habits is more suggestive of a genetic cause than is disease in members with poor health habits
**no matter how consistent or clear a genetic link for disease you might discover, it is FAR FROM CERTAIN PROOF that you too will get the disease |
