| Invitae | RCV000554686 | SCV000636753 | uncertain significance | Perlman syndrome | 2023-08-14 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 657 of the DIS3L2 protein (p.Arg657Cys). This variant is present in population databases (rs113330536, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with DIS3L2-related conditions. ClinVar contains an entry for this variant (Variation ID: 463083). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on DIS3L2 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. |
| Ambry Genetics | RCV002527770 | SCV003701634 | uncertain significance | Inborn genetic diseases | 2020-12-02 | criteria provided, single submitter | clinical testing | The c.1969C>T (p.R657C) alteration is located in exon 16 (coding exon 15) of the DIS3L2 gene. This alteration results from a C to T substitution at nucleotide position 1969, causing the arginine (R) at amino acid position 657 to be replaced by a cysteine (C). The p.R657C alteration is predicted to be tolerated by in silico analysis. Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
