Expression of beta ig-h3 in sub-epithelial matrix and posterior collagenous layer of Fuchs' dystrophy is consistent with the synthesis of new extracellular matrices by epithelial and endothelial tissues. beta ig-h3 mRNA in corneal epithelium further supports an epithelial source of this protein.
To characterize histologically Descemet's membrane in an early-onset Fuchs corneal dystrophy (FCD) COL8A2 mutant and compare these findings with corneas from late-onset FCD and normal corneas.
The absence of pathogenic mutations identified in the COL8A1 or COL8A2 genes in affected members of 15 pedigrees with familial FECD indicates that other genetic factors are involved in the development of this autosomal dominant corneal dystrophy.
The identification of a novel missense mutation in only one of the patients implied that TCF8 does not play a significant role in the pathogenesis of FECD in this Chinese population.
Our data suggests that SLC4A11 haploinsufficiency and gradual accumulation of the aberrant misfolded protein may play a role in FECD pathology and that reduced levels of SLC4A11 influence the long-term viability of the neural crest derived corneal endothelial cells.
To perform a genome-wide linkage screen with a single-nucleotide polymorphism (SNP) linkage panel to identify regions of genetic linkage in Fuchs endothelial corneal dystrophy (FECD) and to analyze affected individuals for mutations in the COL8A2 gene.
To identify the disease locus associated with autosomal dominant Fuchs corneal dystrophy (FCD) in a large family and to compare the progression of severity in families mapped to the FCD1 and FCD2 loci.
