📝 英文原版摘要
Proceedings of the National Academy of Sciences, Volume 123, Issue 10, March 2026. <br />SignificanceWe analyzed a missense variant in DNA Ligase 1 (K845N) that is associated with a profound delay in the onset of Huntington’s disease (HD). We find that K845N enhances substrate discrimination toward mismatched substrates, thus increasing ...
