Genes affected

FBXL13 (HGNC:21658): (F-box and leucine rich repeat protein 13) Members of the F-box protein family, such as FBXL13, are characterized by an approximately 40-amino acid F-box motif. SCF complexes, formed by SKP1 (MIM 601434), cullin (see CUL1; MIM 603134), and F-box proteins, act as protein-ubiquitin ligases. F-box proteins interact with SKP1 through the F box, and they interact with ubiquitination targets through other protein interaction domains (Jin et al., 2004 [PubMed 15520277]).[supplied by OMIM, Mar 2008]

The c.1598T>G (p.V533G) alteration is located in exon 16 (coding exon 14) of the FBXL13 gene. This alteration results from a T to G substitution at nucleotide position 1598, causing the valine (V) at amino acid position 533 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
