Hi ,

I have Microarray dataset of Gene expression. I want to predict CNV based on this Microarray Gene expression dataset. Is there any possibility to do this?. Is there any tools available which can help me.?

I've seen CNV processing based on high throughput sequencing and genotyping arrays, but doesn't Microarray tackle RNA expression? Do you think it will be a reliable dataset for Copy Number Variants? How would one deconvolute natural differential expression from DE resulting from a duplication/deletion?

There are many microarrays that specifically target copy number. Also, there is a long-running project, called AROMA, that has developed methods to derive copy number from SNP arrays. In this case, the user is indeed referring to a cDNA microarray that aims to measure gene expression.

To be able to reliably predict CNVs from gene expression data, a requirement would be a more or less simple and predictable relation between copy number and gene expression variations. However, it seems this is not the case: copy number and gene expression have a complex (and not fully understood) relationship. See the review The impact of human copy number variation on gene expression, for example.
