Subsequently, discovery of genetic rearrangements involving TMPRSS2 with other 3' erythroblastosis virus E26 transformation‐specific (ETS) transcription factor family members such as ETV1 (∼5%), ETV4 (∼5%), or ETV5 (∼1%) led to further classification of PCa. Here, TMPRSS2 is linked to posterior cortical atrophy.
