17721297 Observational study of genotype prevalence. (HuGE Navigator)
17721297 The absence of pathogenic mutations in COL8A1 and COL8A2 in patients with keratoconus indicates that other genetic factors are involved in the pathogenesis of this corneal ectatic disorder.
17471329 Microscopic and electron microscopic examination revealed pathological changes in Descemet's membrane of L450W COL8A2 mutants that were consistent with several-fold increased growth of the extracellular matrix.
16936088 The absence of pathogenic mutations identified in the COL8A1 or COL8A2 genes in affected members of 15 pedigrees with familial FECD (Fuchs endothelial corneal dystrophy) indicates that other genetic factors are involved.
16908762 Alpha2(VIII) collagen supported endothelial cell attachment in a dose-dependent manner, with an 18-fold higher affinity for endothelial cells.
15914606 A novel pathogenic L450W COL8A2 mutation was identified and its highly distinctive pathology characterized. This indicates that COL8A2 mutations give rise to a rare subtype of FCD (Fuchs corneal dystrophy).
15851557 No pathogenic mutations were identified in the COL8A2 gene or in several positional candidate genes in a series of patients, indicating that other genetic factors are involved in the development of this autosomal dominant corneal dystrophy.
15175909 The R155Q and T502M mutations of COL8A2 may not be the causative defect in the Japanese Fuchs' endothelial corneal dystrophy and posterior polymorphous dystrophy patients examined in this study.
