PRSS1 and glioblastoma: ULR identified 10 somatic mutations as predictors of LTS with p < 0.05 (none of which are statistically significant after Bonferroni or Benjamini-Hochberg adjustment of p-values), among these are mutations in genes whose somatic variants are well-known to correlate with GBM survival time such as IDH1 and PRSS1 (S2 Table).
