SPOP and posterior cortical atrophy: Conversely to subclonal TP53 mutations, some alterations seem to represent early (‘truncal’) oncogenic driver events, as they were clonally present throughout all samples from the primary disease and also shared by the metastases: SPOP p.F133V (a well‐described hotspot mutation in PCa [34, 35]), BRAF p.K601E (a potentially activating variant, which has previously been reported in PCa [21]), and TMPRSS2:ERG or ETV1 rearrangements, in keeping with the early and clonal nature of this alteration [36].
