PTEN and posterior cortical atrophy: To address the relationship between PITX1 and genomic instability, we compared data on recurrent deletions prevailing in ERG-fusion positive (10q23, PTEN; 3p14, FOXP1) [37,38] or ERG-fusion negative PCa (5q21, CHD1; 6q15, MAP3K7) from a previous analysis of the TMA [39,40].
