Three novel mutations of the PAX6 gene in Japanese aniridia patients

Abstract

Mutations in the PAX6 gene of Japanese aniridia patients were analyzed. Four types of mutations including one known (474delC) and three novel (786_787ins10, 678_688del11 and 572_575delAATCins14) were found in six patients from four families. A patient with the mutation 572_575delAATCins14 also manifested VATER association. This is the first case of aniridia accompanied by VATER association. All of mutations found in this study are frameshift type, resulting in premature termination of translation. The database for PAX6 gene mutation has been made using a graphical data display system MutationView (http://mutview.dmb.med.keio.ac.jp/). © 2007 The Japan Society of Human Genetics and Springer.
