Genes affected

LORICRIN (HGNC:6663): (loricrin cornified envelope precursor protein) This gene encodes loricrin, a major protein component of the cornified cell envelope found in terminally differentiated epidermal cells. Mutations in this gene are associated with Vohwinkel's syndrome and progressive symmetric erythrokeratoderma, both inherited skin diseases. [provided by RefSeq, Jul 2008]
