| Invitae | RCV000467072 | SCV000551633 | uncertain significance | Perlman syndrome | 2023-11-17 | criteria provided, single submitter | clinical testing | This sequence change replaces tyrosine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 721 of the DIS3L2 protein (p.Tyr721Cys). This variant is present in population databases (rs371864654, 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: 410772). 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 not expected to disrupt DIS3L2 protein function with a negative predictive value of 80%. 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 | RCV004022815 | SCV004857830 | uncertain significance | Inborn genetic diseases | 2023-09-26 | criteria provided, single submitter | clinical testing | The c.2162A>G (p.Y721C) alteration is located in exon 18 (coding exon 17) of the DIS3L2 gene. This alteration results from a A to G substitution at nucleotide position 2162, causing the tyrosine (Y) at amino acid position 721 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
