AUC results =1. Does this data has any validation ?

Question

[sabaghianamir70]

Hello

I have a series of normalized read counts from 10 datasets including normal and treats. I performed Auc analysis for them separately and discover some of my genes had AUC=1 or 100% specificity and sensitivity. All readcounts produced with htseq and all of them normalized. control samples number in each dataset were 10. and treat samples number were between 10-50. So based of these input : 1- does AUC analysis even validates here ? 2- Is there any thing wrong which make AUC=1. All other values including Standard erorrs and significant p values are ok.

Thanks
