In accordance with the observed decreased expression of miR‐200 family in BAV patients, both ZEB1 and ZEB2 had significantly higher expression in nondilated aortas when compared to TAV‐ND (P = 0.0001 for ZEB1 and P = 0.0002 for ZEB2), but both transcription factors expression remained unchanged as a result of aneurysm in BAV‐D patients. The gene discussed is ZEB1; the disease is aneurysm.
