# MONDO Search Help

### **Allowed ontology (MONDO IDs)**

[MONDO (Monarch Disease Ontology)](https://obofoundry.org/ontology/mondo.html) merges several different vocabularies into a single ontology structure, including some non-human disease ontologies. These include [Orphanet](http://www.orpha.net/consor/cgi-bin/index.php), [OMIM](https://www.omim.org/), [Disease Ontology (DO)](http://www.disease-ontology.org/), [NCIt](https://ncit.nci.nih.gov/ncitbrowser/), [EFO](https://www.ebi.ac.uk/efo/) and others.

The interfaces support the entry of MONDO IDs, which may be mapped to one or more different ontologies such as those listed above.

### **Finding a MONDO term**

Use the [MONDO OLS Search](https://www.ebi.ac.uk/ols/ontologies/mondo) to find the correct disease term (this search is linked from the disease selection screen in the ClinGen interfaces). Note: be certain you are only searching MONDO in the OLS as it supports the search of a wide variety of ontologies:

### Using MONDO search

The MONDO OLS has a type-ahead function. Below is an example of what is found after typing “preimpla”

If you select a term from the first list or use the search button, you will be taken to a search results page with filtering options.

![Search results page](https://453646021-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FzjRMfxI6chghHwy4VhQv%2Fuploads%2FndyRPIlbkhpFGl4WDpNG%2Fmondo%20results%201.png?alt=media\&token=755f8379-4655-4132-ae94-c3a6cfa5bccf)

If you "jump to" a term with a MONDO ID, you will be taken directly to the page for that ID.

![MONDO ID page](https://453646021-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FzjRMfxI6chghHwy4VhQv%2Fuploads%2FiS6sYAq6JsCHoSdQhvZ7%2Fmondo%20results%202.png?alt=media\&token=6640ee88-961b-433f-a9b8-62702e95cdc6)

If the term is correct, copy the “ID” (“MONDO:0000218” in this example). You can click <img src="https://453646021-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FzjRMfxI6chghHwy4VhQv%2Fuploads%2FfwX9mYFnzrjyCZVIisVz%2Fmondo%20copy%20button.png?alt=media&amp;token=29b86c12-4f9b-41fc-a0b4-2eef5b8cbedf" alt="" data-size="line">**Copy** in the OLS header to save the MONDO ID for that entry to your clipboard.

Return to the curation interface paste the MONDO ID into the "Add Disease" selection screen:

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://vci-gci-docs.clinicalgenome.org/vci-gci-docs/external-tools/mondo-search-help.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.
