Genogram Symbols Reference

Complete guide to standard genogram notation

Genogram symbols are standardized shapes and lines used to represent family members and their relationships. The basic symbols are: square = male, circle = female, diamond = unknown gender. An X through any shape indicates deceased. Relationship lines connect symbols: solid line = marriage, dashed line = engagement, zigzag line = conflict. These symbols were established by Murray Bowen (1978) and standardized by McGoldrick, Gerson, and Petry (1985, 2008).

Below is a complete reference of all genogram symbols organized by category. For in-depth explanations with clinical context, see our detailed symbols guide.

Health Condition Symbols

Genograms track hereditary and significant health conditions. The quadrant system divides the symbol into sections for different condition categories.

WebGeno's Quadrant System

Traditional genogram practice uses shading or filling to indicate health conditions. WebGeno implements its own quadrant-based system for clear visual organization:

Position Category Example Conditions
Top-Left Cardiovascular Heart disease, hypertension, stroke
Top-Right Mental / Neurological Depression, anxiety, bipolar, dementia, ADHD
Bottom-Left Cancer Breast, colon, lung, prostate, ovarian
Bottom-Right Metabolic / Endocrine Diabetes, thyroid disorders, obesity
Outer Ring Other Categories Respiratory, autoimmune, musculoskeletal

Note: This quadrant layout and outer ring are WebGeno's implementation. WebGeno uses 13 distinct visual patterns (stripes, dots, crosshatch, etc.) to differentiate conditions, ensuring clarity in both color and black-and-white printing. See our features page for details on the 42 predefined conditions.
