Although most mutations in the PAX6 gene are responsible for aniridia, some mutations can be connected to some other ocular disorders including: microphthalmia, microcornea, foveal hypoplasia, ocular coloboma, keratitis, congenital cataract, Gillespie syndrome, Peters anomaly, and morning glory disc anomaly (Mirzayans et al. 1995; van Heyningen and Williamson 2002; Azuma et al. 2003; Tzoulaki et al. 2005; Wang et al. 2012). The gene discussed is PAX6; the disease is isolated aniridia.
