Introduction/Background: Major Histocompatibility Class II (MHC-II) molecules are transmembrane proteins that are essential to the development of the normal adaptive immune response. The genes that encode the MHCII include the Regulatory Factor X-Associated Ankyrin Containing Protein (RFXANK), Regulatory Factor X-Associated Protein (RFXAP), Regulatory Factor X, 5 (RFX5), and MHC-II transactivator (CIITA) proteins. Homozygous mutations in these genes lead to MHC-II Deficiency Syndrome and have been associated with early onset and severe respiratory and...
