TMPRSS2 and posterior cortical atrophy: It is noteworthy that three PCa-associated splice variants identified in previous studies, Bcl-xL, FGFR2-IIIc and TMPRSS2-ERG+72 (refs 14, 15, 20), did not exhibit DS in our AA PCa versus EA PCa comparison (Supplementary Data 1), suggesting that these variants may contribute to PCa progression/aggressiveness in a race-independent manner.
