Current treatments address individual symptoms rather than the underlying cause of disease. Because all patients preserve a normal but epigenetically silenced maternal copy of these genes, activation of this copy offers a potential disease-modifying therapy. Here, we investigated the epigenetic regulator SMCHD1. First, we demonstrated that SMCHD1 represses the PWS locus in both mice and humans, supporting its relevance as a therapeutic target. Second, we found that SMCHD1 represses the entire PWS locus in neural lineages, extending its previously known role beyond only part of the cluster.
