Disease ID:1130
Name:Corneal dystrophy, Fleck
Associated with:1 target
CFD | corneal dystrophy, Francois-Neetens speckled ro flecked
A rare, autosomal dominant disease which causes the formation of numerous tiny, dot-like white flecks scattered in all layers of the corneal stroma. A few patients present with photophobia, but the majority are asymptomatic.

phosphoinositide kinase, FYVE-type zinc finger containing
Role:  The PIKFYVE protein kinase regulates the sorting and traffic of peripheral endosomes that contain lysosomally directed fluid phase cargo, by controlling the morphogenesis and function of multivesicular bodies. Mutations in the gene are associated with CFD, and appear to cause symptomatic corneal flecks composed of abnormal keratinocytes swollen with intracytoplasmic vesicles containing complex lipids and glycosaminoglycans.
