Genes affected

FBXL20 (HGNC:24679): (F-box and leucine rich repeat protein 20) Members of the F-box protein family, such as FBXL20, 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.617C>T (p.T206M) alteration is located in exon 8 (coding exon 8) of the FBXL20 gene. This alteration results from a C to T substitution at nucleotide position 617, causing the threonine (T) at amino acid position 206 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
