The relative expression level of ETS family genes previously found rearranged in PCa (ERG, ETV1, ETV4, ETV5), Ewing sarcoma (FLI1, ERG, ETV1, ETV4, and FEV) or leukaemia (ERG and ETV6), and additional ETS genes found overexpressed (ELK4) or localised between two genes commonly rearranged (ETS2), was analysed with TaqMan low-density arrays, followed with FISH, reverse transcription polymerase chain reaction (RT-PCR), and sequencing analyses in selected cases [9]. Here, FLI1 is linked to posterior cortical atrophy.
