Genes affected

FBXO31 (HGNC:16510): (F-box protein 31) This gene is a member of the F-box family. Members are classified into three classes according to the substrate interaction domain, FBW for WD40 repeats, FBL for leucing-rich repeats, and FBXO for other domains. This protein, classified into the last category because of the lack of a recognizable substrate binding domain, has been proposed to be a component of the SCF ubiquitination complex. It is thought to bind and recruit substrate for ubiquitination and degradation. This protein may have a role in regulating the cell cycle as well as dendrite growth and neuronal migration. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2013]

The c.1348G>A (p.V450M) alteration is located in exon 8 (coding exon 8) of the FBXO31 gene. This alteration results from a G to A substitution at nucleotide position 1348, causing the valine (V) at amino acid position 450 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
