Genes affected
FBXL4 (HGNC:13601): (F-box and leucine rich repeat protein 4) This gene encodes a member of the F-box protein family, which are characterized by an approximately 40 amino acid motif, the F-box. F-box proteins constitute one subunit of modular E3 ubiquitin ligase complexes, called SCF complexes, which function in phosphorylation-dependent ubiquitination. The F-box domain mediates protein-protein interactions and binds directly to S-phase kinase-associated protein 1. In addition to an F-box domain, the encoded protein contains at least 9 tandem leucine-rich repeats. The ubiquitin ligase complex containing the encoded protein may function in cell-cycle control by regulating levels of lysine-specific demethylase 4A. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2013]

Submissions by phenotype
not provided Uncertain:2
Uncertain significance, criteria provided, single submitter | clinical testing | GeneDx | Sep 10, 2019 | In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge - |
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jun 22, 2022 | 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 FBXL4 protein function. ClinVar contains an entry for this variant (Variation ID: 373158). This variant has not been reported in the literature in individuals affected with FBXL4-related conditions. This variant is present in population databases (rs780707718, gnomAD 0.07%). This sequence change replaces serine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 342 of the FBXL4 protein (p.Ser342Cys). - |
not specified Uncertain:1
Uncertain significance, flagged submission | clinical testing | GeneDx | Nov 28, 2016 | The S342C variant in the FBXL4 gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The S342C variant was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. The S342C variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. However, this substitution occurs at a position that is not conserved and in silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. We interpret S342C as a variant of uncertain significance. - |
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.1025C>G (NP_036292.2:p.Ser342Cys) [GRCH38: NC_000006.12:g.98905504G>C] variant in FBXL4 gene is interpretated to be a Uncertain Significance - Conflicting 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. BP4:Computational evidence/predictors indicate no impact on the FBXL4 structure, function, or protein-protein interaction. Based on this evidence code ClinGen Pathogenicity Calculator (PMID:28081714) suggested that the variant is Uncertain Significance - Conflicting Evidence. - |
