Further support of the role of CYP1B1 in patients with Peters anomaly.

PURPOSE: Peters anomaly is a developmental anomaly of the eye frequently associated with glaucoma. The aim of this study was to further define the molecular basis of this condition. METHODS: The role of four candidate genes implicated in ocular development or glaucoma, PAX6, PITX2, MYOC, and CYP1B1, was studied in 15 patients with Peters anomaly. Mutational analysis used a combination of single strand conformation polymorphism (SSCP) and direct cycle sequencing. RESULTS: Four mutations in CYP1B1 were found in 3/15 (20%) affected individuals compared with 1/140 (0.7%) control individuals. CONCLUSIONS: This study supports the role of CYP1B1 as a causative gene in Peters anomaly. Furthermore, this emphasizes the broad range of phenotypic expression for CYP1B1 mutations, and its role in eye development.
