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.
In this study, 2 male siblings who had been diagnosed with brittle cornea syndrome underwent ophthalmologic and genetic assessment.
A novel homozygous deletion c.2972del, p.(Pro991Hisfs62) in the ZNF469 gene was identified in a Spanish family.
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.
本研究旨在描述 2 名西班牙脆性角膜综合征同胞的临床、断层和遗传发现,并报告一个新的 ZNF469 基因突变,该突变与该疾病的发展有关。
本研究纳入了 2 名已被诊断为脆性角膜综合征的男性同胞,并进行了眼科和基因评估。
在一个西班牙家庭中发现了 ZNF469 基因中的一个新的纯合缺失 c.2972del,p.(Pro991Hisfs62)。
这是西班牙家族中 ZNF469 突变导致脆性角膜综合征的首次报道。该新突变的发现扩大了 ZNF469 变异体在该综合征中的作用范围。
