About this genogram
A three-generation genogram illustrating the autosomal recessive inheritance pattern of sickle cell disease. Both parents are carriers with sickle cell trait (HbAS). Among their three children, one has sickle cell disease (HbSS), one is a carrier (HbAS), and one is unaffected (HbAA). Extended family members show the distribution of carriers across maternal and paternal lines, demonstrating how the trait can be present without symptoms for generations.
Medical analysis
Overview
This 3-generation genogram maps 10 family members with birth years spanning from 1938 to 2001, comprising 5 males and 5 females (1 deceased). The genogram tracks 1 medical/psychological condition category. The index patient is Amara Okonkwo (b. 1995), college student (part-time).
Across 3 generations, the Sickle Cell Disease Inheritance family demonstrates hereditary risk patterns. The founding generation includes Samuel, Grace, Joseph, with 2 members presenting health conditions.
Health conditions
Medical and psychological conditions are documented in 6 of 10 family members (60%). Genetic conditions appear in 6 members (Samuel, Beatrice, Michael...), affecting 3 females and 3 males. The multigenerational prevalence of genetic conditions suggests both genetic predisposition and possible environmental or behavioral transmission pathways.
Genetic counseling perspective
From a genetic counseling perspective, this genogram provides critical risk stratification data. The clustering of genetic conditions 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.
How do you read the Sickle Cell Disease Inheritance genogram?
- 1
Find each person and generation
Squares are males and circles are females, and each row is one generation, oldest at the top. This one has 5 males and 5 females across 3 generations. - 2
Check the status markers
Markers on a symbol add facts about that person: Deceased (X) and Index Patient (Arrow). 1 person is marked deceased. The index person, the focus of the assessment, is Amara Okonkwo. - 3
Follow the family lines
Horizontal lines join partners and vertical lines drop to their children, born left to right in birth order. This genogram uses Marriage and Parent-Child lines. - 4
Read the shading
Shaded symbols mark health conditions: Genetic Conditions. Trace each line of descent to see where a condition recurs and where it stops.
Genogram symbols used in this example
| Symbol | Type | What it means |
|---|---|---|
| Male (Square) | Person Symbols | A square represents a male family member in standard genogram notation. |
| Female (Circle) | Person Symbols | A circle represents a female family member in standard genogram notation. |
| Deceased (X) | Status Markers | An X drawn through the symbol indicates the person is deceased. |
| Index Patient (Arrow) | Status Markers | An arrow pointing to a person identifies them as the index patient — the individual who is the focus of the clinical assessment. |
| Marriage | Structural Relationships | A solid horizontal line connecting two individuals represents a marriage or committed partnership. |
| Parent-Child | Structural Relationships | A vertical line descending from a couple line to a child symbol represents a parent-child relationship. |
| Genetic Conditions | Medical Conditions | Shading indicates inherited genetic disorders (sickle cell, hemophilia, cystic fibrosis, etc.). |

Frequently asked questions
What clinical patterns does the Sickle Cell Disease Inheritance genogram reveal?
The Sickle Cell Disease Inheritance genogram maps multigenerational transmission of psychological patterns, emotional dynamics, and relationship structures. Clinicians use it to identify recurring cycles of behavior, attachment styles, and communication patterns that may inform diagnosis and treatment planning in family therapy.
Why is the Sickle Cell Disease Inheritance genogram important for medical professionals?
The Sickle Cell Disease Inheritance genogram helps medical professionals identify hereditary risk factors by mapping conditions across generations. It supports genetic counseling, preventive care planning, and helps patients understand their family health history for informed decision-making.
What genogram symbols are used in the Sickle Cell Disease Inheritance example?
This genogram uses Male (Square), Female (Circle), Deceased (X), Index Patient (Arrow), Marriage, Parent-Child and Genetic Conditions. All of them follow standard genogram notation, so the chart reads the same way in any genogram program or textbook.
Can I build a genogram like the Sickle Cell Disease Inheritance example?
Yes. Open GenogramAI, choose Create with AI on the dashboard (paid plans) or open a blank genogram and use Ask AI in the editor (any plan), and describe the family in plain words: who is in it, how they are related, key dates and the relationships or health conditions you want to show. The AI draws the symbols and lines, and you can then edit by hand or ask for one change at a time. A family of 10 people like this one takes a short paragraph to describe. The free plan includes 2 genograms and 5 AI credits a month, with PNG export.
