Looking For Snp'S That Are Significantly Differentially Expressed

I have SNP genotyping data from Illumina Bead xpress. I used Genome studio to generate reportfile. I am interested in doing some downstream analysis including looking for SNP's that are significantly differentially expressed in my contro group samples and diseased samples. Any suggestion is greatly appreciated and thanks in advance.

snps expression

SNP array and differential expression? You sound confused. Do you mean to say that you want to calculate whether SNPs are significantly more prevalent in either the disease or control group (i.e., you're doing an association study)?

Yes. I am sorry about the question not being very clear. I am trying to do association study and wanted to see if the SNP's are prevelent in Diseased or the normal group. Could you help me with any package that can be used for downstream analysis ..

There aren't any particular packages needed. You have, in effect, a 2x2 contigency table for each of your SNPs of interest. So, you could just use a Fisher's test, which is the fisher.test() function in R.

You are confused. Transcripts are differentially expressed, not SNPs. Suggest you take some time to figure out what you are trying to do.
