Genes affected

FBXO46 (HGNC:25069): (F-box protein 46) Members of the F-box protein family, such as FBXO46, 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]

Collection Method: clinical testing

The c.1084T>G (p.S362A) alteration is located in exon 2 (coding exon 1) of the FBXO46 gene. This alteration results from a T to G substitution at nucleotide position 1084, causing the serine (S) at amino acid position 362 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
