# CNV Analysis using GenomeStudio or BlueFuse Multi Software Support Webinar

Infinium Copy Number Variations (CNV) are genomic alterations that result in an abnormal number of copies of one or more genes and may contribute to disease development. CNV analysis for Infinium data can be performed using either the cnvPartition plug-in within the GenomeStudio Genotyping Module or BlueFuse Multi Software.

Topics covered:

* How Infinium genotyping data are used for copy number analysis
* Key differences in the functionality and intended use of GenomeStudio/cnvPartition and BlueFuse Multi
* Demonstration of CNV detection analysis using GenomeStudio and the cnvPartition plug-in
* Demonstration of CNV detection analysis using BlueFuse Multi, and the effects of mosaicism on data interpretation

# 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://knowledge.illumina.com/microarray/general/microarray-general-reference_material-list/000008067.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.
