It is usually inherited from the parent, although in some rare cases, it can occur spontaneously. In order to understand the genetic basis of this birth defect, it is important to visualize its inheritance patterns using a medical genogram. By using this tool, physicians and researchers can better understand the presence of Down Syndrome in a family tree, allowing them to anticipate and diagnose a potential diagnosis at an earlier stage. A Down Syndrome Hereditary Medical Genogram is a chart that displays the risk of passing down a genetic condition or trait from generation to generation. This graph can show if there are any significant changes in the probability of an individual or family member having or passing down chromosomal abnormalities like Down syndrome. It also shows the relationship between family members and how certain traits may be shared across generations. Use EdrawMax to download this template.
