We extended this bioinformatic analysis summarizing the percentage of PARK2 CNAs of primary tumors or cancer cell lines with PTEN LOH on 1,953 specimens across 13 different cancer types from the TCGA database to show that there is a strong selection for PARK2 LOH, when one copy of the PTEN gene is missing (Figure S7B). The gene discussed is PRKN; the disease is cancer.
