Labcorp Genetics (formerly Invitae), Labcorp RCV000691555 SCV000819341 uncertain significance Herpes simplex encephalitis, susceptibility to, 1 2022-07-06 criteria provided, single submitter clinical testing 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 have shown that this missense change affects TLR3 function (PMID: 25339207). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 496586). This missense change has been observed in individual(s) with herpes simplex encephalitis (HSE) (PMID: 25339207). This variant is present in population databases (no rsID available, gnomAD 0.01%). This sequence change replaces glycine, which is neutral and non-polar, with aspartic acid, which is acidic and polar, at codon 743 of the TLR3 protein (p.Gly743Asp).
