In ERG-negative cancer, high levels of BCAR1 expression were significantly linked to presence of deletions of PTEN (p < 0.0001), CHD1 (5q21) (p < 0.0001) and MAP3K7 (6q15) (p < 0.0001; Fig. 3b), while these associations were lost in ERG-positive cancer (Fig. 3c). This evidence concerns the gene CHD1 and cancer.
