FBXO11

Chr 2AD

F-box protein 11

Also known as: FBX11, IDDFBA, UBR6, UG063H01, VIT1

This gene encodes an F-box protein that serves as a substrate recognition component of SCF E3 ubiquitin ligase complexes, targeting specific proteins like BCL6, DTL, and SNAI1 for ubiquitination and proteasomal degradation. Mutations cause intellectual developmental disorder with dysmorphic facies and behavioral abnormalities, inherited in an autosomal dominant pattern. The gene is highly constrained against loss-of-function variation (pLI >0.99), indicating that such variants are likely pathogenic when they occur.

Population Constraint (gnomAD)
Highly constrained gene — heterozygous loss-of-function variants are very rare in the population (pLI 1.00). One damaged copy is likely sufficient to cause disease.

Literature Evidence

LOFThe authors stated that deletions/mutations found in DLBCLs are largely monoallelic, indicating that FBXO11 is a haploinsufficient tumor suppressor gene.PMID:22113614
