Genes affected

FBXL18 (HGNC:21874): (F-box and leucine rich repeat protein 18) The protein encoded by this gene is a member of a family of proteins that contain an approximately 40-amino acid F-box motif. This motif is important for interaction with SKP1 and for targeting some proteins for degradation. The encoded protein has been shown to control the cellular level of FBXL7, a protein that induces mitotic arrest, by targeting it for polyubiquitylation and proteasomal degradation. Members of the F-box protein family, such as FBXL18, are characterized by an approximately 40-amino acid F-box motif. F-box proteins interact with SKP1 through the F box, and they interact with ubiquitination targets through other protein interaction domains. [provided by RefSeq, Mar 2016]

The c.1605C>G (p.H535Q) alteration is located in exon 3 (coding exon 3) of the FBXL18 gene. This alteration results from a C to G substitution at nucleotide position 1605, causing the histidine (H) at amino acid position 535 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
