Genes affected

FBXO30 (HGNC:15600): (F-box protein 30) 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 is upregulated in nasopharyngeal carcinoma. [provided by RefSeq, Jul 2008]

Ambry Genetics

Dec 31, 2023

The c.2042G>A (p.R681Q) alteration is located in exon 3 (coding exon 2) of the FBXO30 gene. This alteration results from a G to A substitution at nucleotide position 2042, causing the arginine (R) at amino acid position 681 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
