Researchers from the US and Lebanon profile somatic mutation patterns in dozens of glioblastoma (GBM) tumors from Lebanese patients in a study appearing in PLOS One. Using exome sequencing, the team assessed 60 patient-derived GBM tumor samples from 37 men and 23 women with the aggressive brain tumor type, looking in particular at mutational signatures and somatic variant patterns across 50 genes associated with GBM in other populations.
