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]

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. This variant has not been reported in the literature in individuals with UNC93B1-related conditions. While this variant is present in population databases (rs754871549), the frequency information is unreliable, as metrics indicate poor data quality at this position in the ExAC database. This sequence change replaces arginine with leucine at codon 581 of the UNC93B1 protein (p.Arg581Leu). The arginine residue is weakly conserved and there is a moderate physicochemical difference between arginine and leucine. -
