Summaries for Brittle Cornea Syndrome 2

About this section
NIH Rare Diseases:48 Brittle cornea syndrome (bcs) is a type of connective tissue disorder that mainly affects the eyes, joints and skin. signs and symptoms may include rupture of the cornea after only minor trauma; degeneration of the cornea (keratoconus) or thinning and protrusion of the cornea (keratoglobus); bluish tint in the white part of the eyes (blue sclerae); hypermobile joints; hyperelastic skin; hearing defects; and dental abnormalities. there are 2 types of bcs which are distinguished by the mutated gene that causes the condition. bcs type 1 is caused by mutations in the znf469 gene and bcs type 2 is caused by mutations in the prdm5 gene. bcs is inherited in an autosomal recessive manner. last updated: 2/17/2012

MalaCards based summary: Brittle Cornea Syndrome 2, also known as brittle cornea syndrome, is related to brittle cornea syndrome 1 and musculocontractural ehlers-danlos syndrome, and has symptoms including joint laxity, joint laxity and unspecified visual loss. An important gene associated with Brittle Cornea Syndrome 2 is PRDM5 (PR/SET Domain 5), and among its related pathways are Collagen chain trimerization and Degradation of the extracellular matrix. Affiliated tissues include skin, eye and bone.

UniProtKB/Swiss-Prot:70 Brittle cornea syndrome 2: A disorder characterized by extreme corneal thinning resulting in corneal rupture after minor trauma, blue sclerae, keratoconus or keratoglobus, hyperelasticity of the skin, and hypermobile joints.
