Fan1 huntington's disease
WebApr 16, 2024 · FAN1 nuclease is a modifier of repeat expansion diseases, including Huntington’s disease (HD), fragile X syndrome, and autism. The age of HD onset correlates with ongoing ‘inchworm-like’ repeat expansions (1-3 CAG units/event) in HD brains, and is regulated by three modifiers: The first two, repeat tract length and purity … WebDec 7, 2024 · FAN1 modifies Huntington’s disease onset by unknown mechanisms. Deshmukh et al. demonstrate that FAN1 nuclease binds, dimerizes, and exo-nucleoytically cleaves disease-associated slipped-DNAs. FAN1’s “nibbling” of excess repeats parallels the “inchworm” expansions in patient brains, suggesting a role for FAN1 in regulating repeat …
