Genes affected

UNC93B1 (HGNC:13481): (unc-93 homolog B1, TLR signaling regulator) This gene encodes a protein that is involved in innate and adaptive immune response by regulating toll-like receptor signaling. The encoded protein traffics nucleotide sensing toll-like receptors to the endolysosome from the endoplasmic reticulum. Deficiency of the encoded protein has been associated with herpes simplex encephalitis. [provided by RefSeq, Feb 2014]

UNC93B1 (HGNC:):
