Choriocarcinoma, also known as chorioepithelioma, is related to gestational choriocarcinoma and placental choriocarcinoma. An important gene associated with Choriocarcinoma is H19 (H19 Imprinted Maternally Expressed Transcript), and among its related pathways/superpathways are Peptide hormone metabolism and Transcriptional regulation by the AP-2 (TFAP2) family of transcription factors. The drugs Dactinomycin and Methotrexate have been mentioned in the context of this disorder. Affiliated tissues include placenta and testis, and related phenotypes are Increased shRNA abundance (Z-score > 2) and homeostasis/metabolism
