Invitae RCV000462027 SCV000541441 uncertain significance Werner syndrome 2023-11-13 criteria provided, single submitter clinical testing This sequence change replaces lysine, which is basic and polar, with arginine, which is basic and polar, at codon 1045 of the WRN protein (p.Lys1045Arg). This variant is present in population databases (rs369095273, gnomAD 0.0009%). 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: 404019). 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 arginine 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.
GeneDx RCV001770297 SCV001991972 uncertain significance not provided 2019-04-12 criteria provided, single submitter clinical testing Not observed at a significant frequency in large population cohorts (Lek et al., 2016); Has not been previously published as pathogenic or benign to our knowledge; This variant is associated with the following publications: (PMID: 30019023)
Ambry Genetics RCV002522761 SCV003745159 uncertain significance Inborn genetic diseases 2021-12-13 criteria provided, single submitter clinical testing The c.3134A>G (p.K1045R) alteration is located in exon 25 (coding exon 24) of the WRN gene. This alteration results from a A to G substitution at nucleotide position 3134, causing the lysine (K) at amino acid position 1045 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
GenomeConnect, ClinGen RCV000462027 SCV001423446 not provided Werner syndrome no assertion provided phenotyping only Variant interpretted as Uncertain significance and reported on 05-16-2018 by Lab or GTR ID Invitae. GenomeConnect assertions are reported exactly as they appear on the patient-provided report from the testing laboratory. GenomeConnect staff make no attempt to reinterpret the clinical significance of the variant.
