Differential expression of untranslated regions. The 5′ end of the annotated gene Iigp1 (interferon inducible GTPase 1) contains an unannotated untranslated region (UTR) that is expressed only during infection. The annotated portion was differentially expressed but samples from mock-infected animals had hundreds if not thousands of reads whereas the unannotated 5′ UTR had practically none. This was observed in C57BL/6J mice, suggesting that the Iigp1 gene model is incomplete in the reference annotation.
