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]

Pathogenic, criteria provided, single submitterclinical testingWong Mito Lab, Molecular and Human Genetics, Baylor College of MedicineAug 10, 2017The NM_012160.4:c.1210C>T (NP_036292.2:p.Gln404Ter) [GRCH38: NC_000006.12:g.98899375G>A] variant in FBXL4 gene is interpretated to be a Pathogenic based on ACMG guidelines (PMID: 25741868). This variant meets one or more of the following evidence codes reported in the ACMG-guideline. PVS1:This variant is a predcted null variant in FBXL4 where loss of function is a known mechanism of disease. PM2:This variant is absent in key population databases. PP4:Patient’s phenotype or family history is highly specific for FBXL4. Based on this evidence code ClinGen Pathogenicity Calculator (PMID:28081714) suggested that the variant is Pathogenic. -
