(Submitter supplied) Transparency of the human cornea is necessary for vision. Fuchs Endothelial Corneal Dystrophy (FECD) is a bilateral, heritable degeneration of the corneal endothelium, and a leading indication for corneal transplantation in developed countries. While the early onset, and rarer, form of FECD has been linked to COL8A2 mutations, the more common, late onset form of FECD has genetic mutations linked to only a minority of cases. more...

(Submitter supplied) Fuchs’ endothelial corneal dystrophy (FECD) is a progressive vision impairing disease caused by thickening of Descemet’s membrane and gradual degeneration and loss of corneal endothelial cells. The aim of this study was to identify differentially expressed genes between FECD-affected and unaffected corneal endothelium to gain insight into the pathophysiological mechanisms underlying this disease. Microarray gene expression analysis was performed on total RNA from FECD-affected and unaffected corneal endothelium-Descemet’s membrane (CE-DM) specimens using the Illumina HumanHT-12 v3.0 expression array. more...

(Submitter supplied) RNA-Seq splicing data from the corneal endothelia of FECD patients and controls reveal hundreds of differential alternative splicing events. These include events previously characterized in the context of myotonic dystrophy type 1 and epithelial-to-mesenchymal transition, as well as splicing changes in genes related to proposed mechanisms of FECD pathogenesis.

(Submitter supplied) Genome wide DNA methylation profiling of normal human corneal endothelium and human corneal endothelium from FECD cases. The Illumina Infinium MethylationEPIC 850K BeadChip was used to obtain DNA methylation profiles across approximately 850,000 CpGs in genomic DNA from human corneal endothelium samples. Samples included 11 non-FECD donors, 17 FECD cases.

(Submitter supplied) Defining the normal and age-dependent HCEnC transcriptome will further refine our understanding of the functional roles that the endothelium plays in the cornea and will provide a basis upon which to compare transcriptomes of normal and dystrophic endothelium for the subsequent development of gene-targeted therapies. We used microarrays to comprehensively characterize human corneal endothelial cell (HCEnC) gene expression, age-dependent differential gene expression and to identify expressed genes mapped to chromosomal loci associated with the corneal endothelial dystrophies PPCD1, FECD4 and XECD

(Submitter supplied) PURPOSE: To compare the gene expression profiles of normal human corneal endothelium with Fuchs' corneal endothelium, by using serial analysis of gene expression (SAGE). METHODS: Three pairs of normal human corneas were obtained from eye banks. Thirteen bisected Fuchs' corneal buttons were processed at the time of corneal transplantation. The endothelia of normal and Fuchs'-affected corneas were stripped, and total RNA was isolated. more...

(Submitter supplied) A missense mutation of collagen type VIII alpha 2 chain (COL8A2) gene leads to early onset Fuchs’ endothelial corneal dystrophy (FECD), which can cause blindness through progressive loss of corneal endothelial cells. We established a novel procedure for achieving structural and functional rescue of the post-mitotic corneal endothelium without surgery, using CRISPR/Cas9-based postnatal gene editing in a mouse model of FECD. more...
