Triplex H-DNA structure: the long and winding road from the discovery to its role in human disease

Hisey JA, Masnovo C, Mirkin SM. Triplex H-DNA structure: the long and winding road from the discovery to its role in human disease. NAR Mol Med. 2024 Dec 5;1(4):ugae024. doi: 10.1093/narmme/ugae024. PMID: 39723156; PMCID: PMC11667243. 

H-DNA-forming repeats have been implicated in four REDs: Friedreich's ataxia, GAA-FGF14-related ataxia, X-linked Dystonia Parkinsonism, and cerebellar ataxia, neuropathy and vestibular areflexia syndrome. In this review, we summarize H-DNA's discovery and characterization, evidence for its existence and function in vivo, and the field's current knowledge on its role in physiology and pathology.
