Genes affected

ZNF469 (HGNC:23216): (zinc finger protein 469) This gene encodes a zinc-finger protein. Low-percent homology to certain collagens suggests that it may function as a transcription factor or extra-nuclear regulator factor for the synthesis or organization of collagen fibers. Mutations in this gene cause brittle cornea syndrome. [provided by RefSeq, Jul 2008]
