Fetch RNA seq count data for ~5 genes with mutation status of KRAS

Question

[PK]

Hi everyone,

I am not very familiar with the topic of RNAseq databases, but I need the following data for one specific question:

I wonder about the effect of KRAS mutation on the expression of several genes. What I am looking for, is some tool (possibly in R) to download a bunch of count data for these five genes from different patients for which I also have the mutation status (KRAS mutated or not, more specific would be great, too, of course.)

Can anybody help?

Best, P
