Genes affected
SERPINB8 (HGNC:8952): (serpin family B member 8) The protein encoded by this gene is a member of the ov-serpin family of serine protease inhibitors. The encoded protein is produced by platelets and can bind to and inhibit the function of furin, a serine protease involved in platelet functions. In addition, this protein has been found to enhance the mechanical stability of cell-cell adhesion in the skin, and defects in this gene have been associated with an autosomal-recessive form of exfoliative ichthyosis. [provided by RefSeq, Jan 2017]
HMSD (HGNC:23037): (histocompatibility minor serpin domain containing) This gene encodes a serpin-domain containing protein that may function as a serine protease inhibitor. This gene is primarily expressed in cells of myeloid lineage. A polymorphism in this gene may result in the expression a splice variant that encodes a minor histocompatibility antigen.
