RCV001047387 | SCV001211342 | uncertain significance | Combined oxidative phosphorylation defect type 27 | 2023-07-21 | criteria provided, single submitter | clinical testing | 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 not expected to disrupt CARS2 protein function. ClinVar contains an entry for this variant (Variation ID: 844519). This variant has not been reported in the literature in individuals affected with CARS2-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 tryptophan, which is neutral and slightly polar, at codon 492 of the CARS2 protein (p.Arg492Trp). |
| Ambry Genetics | RCV002553161 | SCV003698491 | uncertain significance | Inborn genetic diseases | 2021-10-14 | criteria provided, single submitter | clinical testing | The c.1474C>T (p.R492W) alteration is located in exon 14 (coding exon 14) of the CARS2 gene. This alteration results from a C to T substitution at nucleotide position 1474, causing the arginine (R) at amino acid position 492 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
