About This Genogram
A three-generation genogram depicting non-BRCA familial breast cancer clustering. The grandmother had bilateral breast cancer at 55, the mother was diagnosed with unilateral breast cancer at 48, and an aunt at 52. BRCA1 and BRCA2 testing was negative across the family, suggesting other genetic or shared environmental factors. The index patient, a 38-year-old female, is under enhanced screening protocols given her strong family history.
How to Read This Genogram
A medical or hereditary genogram uses the same basic symbols as a clinical genogram but adds shading and annotation to track health conditions across generations. Quadrant shading inside a square or circle indicates that the individual carries or has been diagnosed with a specific condition, and a key in the corner of the diagram maps each shading pattern to a particular illness or genetic variant. Reading this diagram from top to bottom reveals which conditions appeared first, which generation carried them forward, and which branches of the family show the heaviest disease burden.
Pedigree analysis in genetic counseling follows a similar structure. A counselor scans the diagram horizontally across each generation to assess prevalence, then traces diagonally to detect autosomal dominant, autosomal recessive, or X-linked inheritance patterns. When multiple individuals in a direct line share a condition, the genogram supports a hereditary hypothesis. When distribution is scattered and skips generations, environmental or multifactorial causes move higher on the differential. This visual summary allows a genetic counselor or primary care physician to communicate complex family health history in a single diagram rather than several pages of narrative notes.
Key Patterns in This Genogram
Hereditary Risk Factors
Genetic and hereditary conditions tracked across multiple generations.
Disease Patterns
How medical conditions cluster and recur within the family tree.
Preventive Insights
Identifying at-risk individuals based on family health history patterns.
Medical Analysis
This 3-generation genogram maps 12 family members with birth years spanning from 1932 to 1993, comprising 6 males and 6 females (2 deceased). The genogram tracks 1 medical/psychological condition category. The index patient is Rachel Kramer (b. 1988), occupational therapist.
Across 3 generations, the Breast Cancer Multi-Generational family demonstrates hereditary risk patterns. The founding generation includes Robert, Ingrid, Thomas, with 2 members presenting health conditions.
Medical and psychological conditions are documented in 5 of 12 family members (42%). Cancer diagnoses appear in 5 members (Robert, Ingrid, Diane...), affecting 4 females and 1 male. The multigenerational prevalence of cancer diagnoses suggests both genetic predisposition and possible environmental or behavioral transmission pathways.
From a genetic counseling perspective, this genogram provides critical risk stratification data. The clustering of cancer diagnoses across generations indicates heritable risk factors. Healthcare providers can use this multigenerational map to guide screening recommendations, inform preventive strategies, and counsel family members about their individualized risk profiles.
Build a Similar Genogram
A practitioner documenting a family similar to this one would typically record three generations of household composition, significant life events such as births, deaths, marriages, and separations, any relevant medical or mental health history, and the quality of key relationships between members. That information comes from a combination of the client's verbal account, intake questionnaires, and, where available, collateral records. The completed diagram captures both the factual structure of the family and the practitioner's clinical observations about relational patterns, making it a reference that can be shared across disciplines or reviewed at future stages of treatment.
GenogramAI's AI genogram generator allows you to build a diagram like this one from a plain-language description of the family. You type or paste a narrative, such as the basic structure and any key relationships or health history you want to include, and the AI parses that text, places the correct symbols, draws the appropriate relationship lines, and arranges the layout automatically. The result is a fully editable diagram that you can refine, annotate, and export for clinical records or educational use. Try the AI genogram creator to generate your own genogram from a text description in seconds.
Genogram Symbols Used in This Example
The following standard genogram symbols appear in the Breast Cancer Multi-Generational. Each symbol follows McGoldrick and Gerson clinical notation conventions.
Person Symbols
- Male (Square)
- A square represents a male family member in standard genogram notation.
- Female (Circle)
- A circle represents a female family member in standard genogram notation.
Status Markers
- Deceased (X)
- An X drawn through the symbol indicates the person is deceased.
- Index Patient (Arrow)
- An arrow pointing to a person identifies them as the index patient — the individual who is the focus of the clinical assessment.
Structural Relationships
- Marriage
- A solid horizontal line connecting two individuals represents a marriage or committed partnership.
- Parent-Child
- A vertical line descending from a couple line to a child symbol represents a parent-child relationship.
Medical Conditions
- Cancer
- Shading indicates any cancer diagnosis, with specifics noted in the individual's record.
