Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the FBH1 gene is commonly pathogenic or not. These statistics are base on transcript: NM_000178150.3. Only rare variants are included in the table.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

• Function: FUNCTION: 3'-5' DNA helicase and substrate-recognition component of the SCF(FBH1) E3 ubiquitin ligase complex that plays a key role in response to stalled/damaged replication forks (PubMed:11956208, PubMed:23393192). Involved in genome maintenance by acting as an anti-recombinogenic helicase and preventing extensive strand exchange during homologous recombination: promotes RAD51 filament dissolution from stalled forks, thereby inhibiting homologous recombination and preventing excessive recombination (PubMed:17724085, PubMed:19736316). Also promotes cell death and DNA double-strand breakage in response to replication stress: together with MUS81, promotes the endonucleolytic DNA cleavage following prolonged replication stress via its helicase activity, possibly to eliminate cells with excessive replication stress (PubMed:23319600, PubMed:23361013). Plays a major role in remodeling of stalled DNA forks by catalyzing fork regression, in which the fork reverses and the two nascent DNA strands anneal (PubMed:25772361). In addition to the helicase activity, also acts as the substrate-recognition component of the SCF(FBH1) E3 ubiquitin ligase complex, a complex that mediates ubiquitination of RAD51, leading to regulate RAD51 subcellular location (PubMed:25585578). {ECO:0000269|PubMed:11956208, ECO:0000269|PubMed:17724085, ECO:0000269|PubMed:19736316, ECO:0000269|PubMed:23319600, ECO:0000269|PubMed:23361013, ECO:0000269|PubMed:25585578, ECO:0000269|PubMed:25772361}.
• Disease: DISEASE: Note=Defects in FBH1 are frequently observed in melanomas, resulting in increased survival in response to replicative stress. Its inactivation may play a role in oncogenic transformation. {ECO:0000269|PubMed:23466708}.
