Loss of RB1 transcript expression is associated with the proneural glioblastoma (GBM) subtype, but is not associated with altered survival. (A) Loss of RB1 transcript expression was identified in 18 of 168 (10.5%) of The Cancer Genome Atlas (TCGA) tumors; these were over-represented in the proneural subtype as defined by Verhaak et al (18) (p < 0.01, adjusted two-sided Fisher exact test). (B) Loss of RB1 transcript expression was not associated with a difference in overall survival on univariate analysis (11).
