Genes affected

FBXL16 (HGNC:14150): (F-box and leucine rich repeat protein 16) Members of the F-box protein family, such as FBXL16, 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.22G>A (p.G8S) alteration is located in exon 2 (coding exon 1) of the FBXL16 gene. This alteration results from a G to A substitution at nucleotide position 22, causing the glycine (G) at amino acid position 8 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
