# Creating a family tree

Build a pedigree via the visual tool.

![](/files/1Y48cJDaa7K3yAQfk5cu)

It is ideal that a proband selected for case analysis is affected and has disease phenotype(s).

You can add a Father, a Mother, a Sibling, or a Child to any family member, starting with the Proband. To do this, choose their icon, then click on the Add family member button in the bottom right corner of the pedigree builder to select a family member.

More information about the pedigree symbols can be found [here](/emedgene/emedgene-analyze-manual/launching-analysis/creating_a_single_case/2.-family-tree/family_tree_legend.md).

To delete a family member, choose their icon, then click on the Delete Subject button in the top right corner of the Add patient information panel.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.connected.illumina.com/emedgene/emedgene-analyze-manual/launching-analysis/creating_a_single_case/2.-family-tree/create_a_family_tree.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
