# Merge Cases

Connected Insights supports merging RNA and DNA cases with the same case subject. For instructions on how to change the case subject, refer to [Case Details](/connected-insights/interpret-and-report/cm-cases-details.md). Merge cases as follows.

2. Select the **Overview** tab, and then select **Case Details** to open the Case Details pane.
3. Select **Related Cases**. All cases (including DNA, RNA, and DNA+RNA cases) with the same case subject display.
4. Select **Merge Cases**.
5. Configure the case as follows.\
   a. To merge a DNA case, select **Select DNA Case** and choose from a drop-down list with applicable DNA cases.\
   b. To merge an RNA case, select **Select RNA Case** and choose from a drop-down list with applicable RNA cases.\
   c. \[Optional] To change the case number, enter a new case ID.\
   d. Select the applicable definition from the Confirm Test Definition drop-down list.\
   This option defaults to the DNA case test definition.\
   e. Select the disease associated with the merged case.\
   This field can be the same or different disease from the one that is in the DNA and RNA cases that are you merging.
6. Select **Confirm**.
7. Make sure that the new case displays under the Case Timeline in the Case Details sidebar. When the merged case is selected, Connected Insights indicates that the case was created from merging the RNA and DNA cases.

## 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/connected-insights/interpret-and-report/cm-cases-details/cm-merge-cases.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.
