Hello all,

I have generated a hypothesis using RNA-Seq data on ~100 breast tumor and matched normal samples from TCGA. Now, I need to test this hypothesis in a even larger number of breast tumor and matched normal samples other than TCGA. I searched for it and found METABRIC data (http://www.cbioportal.org/study?id=brca_metabric#summary). However, I can't use it, because they don't have matched normal.

I believe there should be more repositories and efforts curating such data sets, but I just can't find it after spending a substantial amount of time. Can you please suggest me where I need to check?

Thanks in advance!
