New ZNF469 Mutations in Spanish Siblings With Brittle Cornea Syndrome

Purpose: The aim of this study was to describe the clinical, tomographic, and genetic findings of 2 Spanish siblings with brittle cornea syndrome and report a new mutation of gene ZNF469 implicated in the development of this disorder.

Methods: In this study, 2 male siblings who had been diagnosed with brittle cornea syndrome underwent ophthalmologic and genetic assessment.

Results: A novel homozygous deletion c.2972del, p.(Pro991Hisfs62) in the ZNF469 gene was identified in a Spanish family.

Conclusions: This is the first report of a ZNF469 mutation in a Spanish family causing brittle cornea syndrome. The discovery of this new mutation amplifies the spectrum of ZNF469 variants implicated in this syndrome.
