Having access to BCR data for 290 PCa patients from the European validation cohort, we concur that shorter BTLs (< 3900 bp) are correlated with earlier relapse (P = 0.0017; Fig. 4E), while not significant shorter TTLs (< 2000 bp) were more likely to be associated (P = 0.16; Fig. 4F). The gene discussed is BCR; the disease is posterior cortical atrophy.
