Brittle cornea syndrome: A novel mutation

Abstract

Purpose: To report the clinical, tomographic, histopathological and genetic findings of a patient with brittle cornea syndrome and a novel mutation in the ZNF469 gene likely implicated in the development of this disorder. Methods: A 64-year-old man presented with a two-year history of worsening vision in both eyes. The patient and his son were examined by imaging and genetic analysis. Results: The patient exhibited persistent ocular irritation, decreased vision, corneal epithelial defects and corneal stromal opacity. Confocal microscopy revealed that the anterior corneal stroma had a large amount of highly reflective and striated tissue. However, his son had no symptoms. Genetic analysis identified a heterozygous c.1781C > T:p.P594L variation in the ZNF469 gene. Conclusions: We reported a novel mutation in the ZNF469 gene (c.1781C > T:p.P594L) in a patient with brittle cornea syndrome from China, which enriched the spectrum of ZNF469 variants implicated in brittle cornea syndrome.
