RCV001338082 | SCV001531722 | uncertain significance | Herpes simplex encephalitis, susceptibility to, 1 | 2021-04-27 | criteria provided, single submitter | clinical testing | Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The lysine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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. This variant has not been reported in the literature in individuals with TLR3-related conditions. This variant is present in population databases (rs777430960, ExAC 0.002%). This sequence change replaces arginine with lysine at codon 809 of the TLR3 protein (p.Arg809Lys). The arginine residue is moderately conserved and there is a small physicochemical difference between arginine and lysine. |
| Ambry Genetics | RCV004035854 | SCV003528433 | uncertain significance | not specified | 2022-06-17 | criteria provided, single submitter | clinical testing | The c.2426G>A (p.R809K) alteration is located in exon 4 (coding exon 3) of the TLR3 gene. This alteration results from a G to A substitution at nucleotide position 2426, causing the arginine (R) at amino acid position 809 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
