A molecular basis for differential developmental anomalies in Axenfeld-Rieger syndrome.


Pitx2, a bicoid-like homeodomain transcription factor and Dlx2 are two transcriptional markers observed during early tooth development. PITX2 binds to bicoid and bicoid-like elements in the Dlx2 promoter and activates this promoter 30-fold in Chinese hamster ovary cells. Mutations in PITX2 associated with Axenfeld-Rieger syndrome (ARS) provided the first… (More)
