MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes the alpha 2 chain of type VIII collagen. This protein is a major component of the basement membrane of the corneal endothelium and forms homo- or heterotrimers with alpha 1 (VIII) type collagens. Defects in this gene are associated with Fuchs endothelial corneal dystrophy and posterior polymorphous corneal dystrophy type 2. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2014]
PHENOTYPE: Mice homozygous for a knock-out allele exhibit a thinner Descemet's membrane of the cornea. Mice heterozygous or homozygous for an ENU-induced mutation exhibit thin cornea, corneal epithelium, stroma, and Descemet membrane, and enlarged anterior chamber. [provided by MGI curators]
