RCV001858642 | SCV002183553 | uncertain significance | not provided | 2023-10-03 | criteria provided, single submitter | clinical testing | This sequence change replaces leucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 204 of the DARS2 protein (p.Leu204Val). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with clinical features of DARS2-related leukoencephalopathy (Invitae). ClinVar contains an entry for this variant (Variation ID: 801579). 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 DARS2 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 | RCV002549667 | SCV003617731 | uncertain significance | Inborn genetic diseases | 2022-05-01 | criteria provided, single submitter | clinical testing | The c.610C>G (p.L204V) alteration is located in exon 6 (coding exon 6) of the DARS2 gene. This alteration results from a C to G substitution at nucleotide position 610, causing the leucine (L) at amino acid position 204 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
