Abstract

<abstract abstract-type="main"> <title> <x xml:space="preserve">Abstract</x> </title> <p>Cytomegalovirus (CMV) has been proposed to be associated with glioblastoma multiforme, but there are conflicting results including lack of CMV mRNA in transcriptome sequencing data. Here, we utilized deep‐coverage whole‐genome sequencing data to detect latent CMV DNA in surgically resected tumors and to assess the relative proportions of viral and human DNA. We did not find traces of CMV in 52.6 billion DNA sequencing reads from 34 glioblastomas. By statistical analysis, we conclude that should the virus be present in these tumors, the average CMV level does not exceed one virus per 240, 000 tumor cells (99% CI).</p> </abstract>
