Genes affected

IGSF23 (HGNC:40040): (immunoglobulin superfamily member 23) This gene encodes a protein that has one immunoglobulin (Ig) domain and is a member of the immunoglobulin superfamily. Proteins in this superfamily are usually found on or in cell membranes and act as receptors in immune response pathways. [provided by RefSeq, Nov 2011]
