Uncertain significance, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Oct 05, 2022 | This sequence change replaces tyrosine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 251 of the FBXL4 protein (p.Tyr251Cys). This variant is present in population databases (rs758776562, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with FBXL4-related conditions. ClinVar contains an entry for this variant (Variation ID: 437631). 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 FBXL4 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. - |
Uncertain significance, criteria provided, single submitter | clinical testing | GeneDx | Feb 18, 2022 | In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge - |
Mitochondrial DNA depletion syndrome 13 Uncertain:1
Uncertain significance, criteria provided, single submitter | reference population | Wong Mito Lab, Molecular and Human Genetics, Baylor College of Medicine | Aug 10, 2017 | The NM_012160.4:c.752A>G (NP_036292.2:p.Tyr251Cys) [GRCH38: NC_000006.12:g.98917480T>C] variant in FBXL4 gene is interpretated to be a Uncertain Significance - Insufficient Evidence based on ACMG guidelines (PMID: 25741868). This variant meets one or more of the following evidence codes reported in the ACMG-guideline. PM2:This variant is absent in key population databases. Based on this evidence code ClinGen Pathogenicity Calculator (PMID:28081714) suggested that the variant is Uncertain Significance - Insufficient Evidence. - |
