Genes affected

FBXO7 (HGNC:13586): (F-box protein 7) This gene encodes a member of the F-box protein family which is characterized by an approximately 40 amino acid motif, the F-box. The F-box proteins constitute one of the four subunits of the ubiquitin protein ligase complex called SCFs (SKP1-cullin-F-box), which function in phosphorylation-dependent ubiquitination. The F-box proteins are divided into 3 classes: Fbws containing WD-40 domains, Fbls containing leucine-rich repeats, and Fbxs containing either different protein-protein interaction modules or no recognizable motifs. The protein encoded by this gene belongs to the Fbxs class and it may play a role in regulation of hematopoiesis. Alternatively spliced transcript variants of this gene have been identified with the full-length natures of only some variants being determined. [provided by RefSeq, Jul 2008]

For these reasons, this variant has been classified as Pathogenic. This variant disrupts a region of the FBXO7 protein in which other variant(s) (p.Thr22Met) have been determined to be pathogenic (PMID: 19038853, 21347293, 23933751, 26310625). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. This variant has not been reported in the literature in individuals affected with FBXO7-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change affects the initiator methionine of the FBXO7 mRNA. The next in-frame methionine is located at codon 115. -
