| Abstrakt: | Purpose: Mutations in the forkhead transcription factor gene (FOXC1) have been recently shown to cause some cases of juvenile glaucoma associated with a variety of anterior-segment anomalies. The purpose of this study was to investigate the clinical features of Axenfeld-Rieger syndrome caused by FOXC1 mutations in Japanese patients. Patients and Methods: After informed consent was obtained, genomic DNA was isolated from peripheral blood. The DNA-sequence changes were analyzed using single-strand conformation polymorphism analysis and automated sequencing in six Japanese probands with Axenfeld-Rieger syndrome. Results: The authors identified four mutations: pedigree 1 (26-47ins22), 2 (Ile91Ser), 3 (286ins1), and 4 (Arg127His). Two pedigrees showed new mutations in FOXC1. In pedigrees 1,2, and 4, younger generations had iris hypoplasia with severe early-onset glaucoma, whereas their parents had posterior embryotoxon without glaucoma. Pedigree 3 had a single affected person with iris hypoplasia and posterior embryotoxon with a mild increase of intraocular pressure. Conclusion: Four different FOXC1 mutations were found in four of six Japanese pedigrees with Axenfeld-Rieger syndrome. This was a new mutation in two pedigrees that was not found in earlier generations. This study confirms that mutations in this gene cause maldevelopment of the anterior segment of the eye. |
