Familial: a condition where there is a strong family history, but there is not an identified genetic cause.
Family history: Information about health and medical issues in relatives. Family history is one of the most important tools a genetic counselor uses to identify genetic risk. Patterns of specific health issues in an individual’s family history are useful to determine the risk of disease and appropriate genetic testing options.
Pedigree: a family tree using established symbols. Genetic counselors use pedigrees to review the family history and look for patterns that might suggest a risk for genetic disorders or health-related conditions in the family.
