| Invitae | RCV000702434 | SCV000831289 | uncertain significance | Perlman syndrome | 2023-07-12 | criteria provided, single submitter | clinical testing | This variant has not been reported in the literature in individuals affected with DIS3L2-related conditions. 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 sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 713 of the DIS3L2 protein (p.Arg713Cys). 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. 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) performed at Invitae indicates that this missense variant is expected to disrupt DIS3L2 protein function. ClinVar contains an entry for this variant (Variation ID: 579206). |

RCV003420252 | SCV004107423 | uncertain significance | DIS3L2-related condition | 2022-11-09 | criteria provided, single submitter | clinical testing | The DIS3L2 c.2137C>T variant is predicted to result in the amino acid substitution p.Arg713Cys. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0039% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/2-233198676-C-T). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. |
