Another novel FOXE3 sequence change, c.571–579dup (p.Tyr191_Pro193dup), was identified in a patient with aniridia, mild lens opacities, and some additional ocular defects; this patient was also found to carry a nonsense mutation in PAX6. PAX6 mutations were identified in two additional probands with aniridia and cataracts. The gene discussed is FOXE3; the disease is isolated aniridia.
