Fan1 huntington's disease
WebFeb 1, 2024 · Huntington’s disease (HD) is a dominantly inherited neurodegenerative condition caused by expansion of a CAG trinucleotide repeat in the huntingtin ( HTT) gene ( 1 ). The CAG region translates into an expanded polyglutamine stretch close to the N-terminus of the HTT protein which confers a toxic gain of function.

WebDec 7, 2024 · FAN1 is the strongest disease modifier for seven CAG expansion diseases, including HD, SCA1-3, SCA6, SCA7, and SCA17 ( Deshmukh et al., 2024 ). Recent data suggest paths by which FAN1 may act on repeat instability. WebJul 2, 2024 · A recent genome-wide association study of Huntington disease (HD) implicated genes involved in DNA maintenance processes as modifiers of onset, including multiple genome-wide significant signals in a chr15 region containing the DNA repair gene Fanconi-Associated Nuclease 1 (FAN1).Here, we have carried out detailed genetic, …
WebCAG repeat expansion in the HTT gene drives Huntington’s disease (HD) pathogenesis and is modulated by DNA damage repair pathways. In this context, the interaction between FAN1, a DNA-structure-specific nuclease, and MLH1, member of the DNA mismatch repair pathway (MMR), is not defined.
