| Invitae | RCV000535084 | SCV000629678 | uncertain significance | Werner syndrome | 2022-09-23 | criteria provided, single submitter | clinical testing | This sequence change replaces tyrosine, which is neutral and polar, with histidine, which is basic and polar, at codon 1034 of the WRN protein (p.Tyr1034His). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with WRN-related conditions. ClinVar contains an entry for this variant (Variation ID: 458442). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The histidine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. |
