Atypical structures of GAA/TTC trinucleotide repeats underlying Friedreich’s ataxia: DNA triplexes and RNA/DNA hybrids

The authors intended the study to provide a ‘rationale for the discovery and characterization of the non-B DNA regulatory structures involved in the formation of the RNA:DNA interactome’. However, experimental data with molecular resolution for these non-B DNA structures is noticeably scarce. We believe that structural studies such as ours can meaningfully contribute in the creation of such a roadmap.
