Ebstein Malformation of the Tricuspid Valve, also known as ebstein anomaly of the tricuspid valve, is related to ebstein anomaly and accessory tricuspid valve tissue. An important gene associated with Ebstein Malformation of the Tricuspid Valve is CDK8 (Cyclin Dependent Kinase 8), and among its related pathways/superpathways is RNA Polymerase II Transcription Initiation And Promoter Clearance. Affiliated tissues include heart and liver, and related phenotypes are respiratory insufficiency and fatigue
