Specifically, we identified and replicated 2 novel DMPs between GD and HD (in KLF9 and MDC1), provide suggestive evidence for a further 2 DMPs (in ZMIZ1 and HORMAD2-AS1) and identified and replicated a region within CUTA that was differentially methylated between GD and HD. This evidence concerns the gene ZMIZ1 and Huntington disease.
