Associations of recurrent deletion events of selected genes with Gleason score and race in TCGA and AAPC cohorts. Left: Amplification frequencies were associated with race and Gleason score while controlling for age using samples from TCGA and AAPC cohorts with genome-wide copy number ratio data (AFR: 157, EUR: 392). A purple dot indicates statistically significant association with race (FDR < 0.05). The solid black line represents a 1:1 relationship between AFR and EUR patients. Genes that did not have a significant association (FDR >= 0.05) with race are indicated by an open dot. Right: Deletion frequencies for PTEN, ZFHX3, and ETV3 are shown in AFR and EUR men.
