A novel PITX2 mutation in a Chinese family with Axenfeld-Rieger syndrome
PURPOSE Axenfeld-Rieger syndrome (ARS) is an autosomal dominant disorder characterized by extraocular anomalies and developmental defects of the anterior segment. PITX2 (paired-like homeodomain transcription factor 2) is considered the major causative gene. In this study, we characterized the molecular defect in PITX2 in a Chinese family with ARS. METHODS Two generations of the family with AR...
متن کاملPotential novel mechanism for Axenfeld-Rieger syndrome: deletion of a distant region containing regulatory elements of PITX2.
PURPOSE Mutations in PITX2 are associated with Axenfeld-Rieger syndrome (ARS), which involves ocular, dental, and umbilical abnormalities. Identification of cis-regulatory elements of PITX2 is important to better understand the mechanisms of disease. METHODS Conserved noncoding elements surrounding PITX2/pitx2 were identified and examined through transgenic analysis in zebrafish; expression p...
متن کاملCurrent molecular understanding of Axenfeld-Rieger syndrome.
Axenfeld-Rieger syndrome (ARS) is a rare autosomal dominant inherited disorder affecting the development of the eyes, teeth and abdomen. The syndrome is characterised by complete penetrance but variable expressivity. The ocular component of the ARS phenotype has acquired most clinical attention and has been dissected into a spectrum of developmental eye disorders, of which open-angle glaucoma r...
متن کاملNovel c.300_301delinsT Mutation in PITX2 in a Korean Family with Axenfeld-Rieger Syndrome
Axenfeld-Rieger syndrome (ARS) is characterized by anomalies of the anterior segment of the eye and systemic abnormalities. Mutations in the FOXC1 and PITX2 genes are underlying causes of ARS, but there has been few reports on genetically confirmed ARS in Korea. We identified a novel PITX2 mutation (c.300_301delinsT) in 2 Korean patients from a family with ARS. We expand the spectrum of PITX2 m...
