Detection of alternative DNA structures and its implications for human disease

Matos-Rodrigues G, Hisey JA, Nussenzweig A, Mirkin SM. Detection of alternative DNA structures and its implications for human disease. Molecular Cell. 2023 Oct;83(20):3622-3641. DOI: 10.1016/j.molcel.2023.08.018. PMID: 37863029. 

 The most well-known REDs include Huntington’s disease (HD), fragile X syndrome (FXS), and Friedreich’s ataxia (FRDA), which are caused by the expansion of (CAG)n, (CGG)n, and (GAA)n repeats, respectively. Thus, DNA sequences prone to formalternative DNA structures are highly frequent in the human genome and associated with several human diseases.
