- **Grandparents**: GRFTH (grandfather), GRMTH (grandmother),
  PGRFTH (paternal grandfather), MGRMTH (maternal grandmother).
- **Children**: SON, DAU, NCHILD (natural child), STPSON, STPDAU.
- **Extended**: UNCLE, AUNT, COUSN (cousin), NEPHEW, NIECE.

## Common Heritable Conditions

## Status

- partial, completed, entered-in-error, health-unknown.
- Use **health-unknown** for adopted patients or unknown family members.

## Age and Deceased

- **age**: Use Age data type (e.g., onset at age 55) or ageRange.
- **deceasedBoolean** / **deceasedAge** / **deceasedDate**: Include for deceased relatives.
  Common pattern: father deceased at age 62 from MI.
- **bornDate**: Include approximate birth year when relevant.

## Clinical Patterns

- **Three-generation history**: Include parents + grandparents + siblings minimum.
- **Cancer clustering**: Multiple first-degree relatives with same cancer type →
  suggest genetic testing referral.
- **Cardiovascular family**: Father MI at 55, paternal grandfather stroke at 60,
  brother hypertension at 40.
- **Diabetes family**: Mother T2DM, maternal grandmother T2DM, sibling pre-diabetes.
- **Unknown history**: Adopted patients — use status "health-unknown".
