RB1 and posterior cortical atrophy: Similarly, Calagua et al. [52] found that the deletion of BRCA and/or RB1 was more frequent in their subset of 11 immunogenic patients than in the localized PCa data obtained from the TCGA Firehose legacy (BRCA2 deletion: p = 0.053, RB1 deletion: p = 0.017, co-deletion of BRCA2/RB1: p = 0.053, focal co-deletion of BRCA2/RB1: p = 0.039; n = 489).
