FBH1
Chr 10ADF-box DNA helicase 1
Also known as: FBXO18, Fbx18, hFBH1
This protein functions as a 3'-5' DNA helicase that maintains genome stability by regulating DNA replication fork processing and homologous recombination, and also serves as a component of an E3 ubiquitin ligase complex. Mutations cause autosomal dominant early-onset epilepsy with or without developmental delay, neurodevelopmental disorder with speech impairment and dysmorphic features, or hypocalciuric hypercalcemia. The gene is highly constrained against loss-of-function variants (LOEUF 0.479), indicating that such variants are likely pathogenic.
