With an incidence of ~1 in 800 births, Down syndrome (DS) is the most com- mon chromosomal condition linked to intellectual disability worldwide. While the genetic basis of DS has been identified as a triplication of chromosome 21 (HSA21), the genes encoded from HSA 21 that directly contribute to cognitive de fi cits remain incompletely understood. Here, we found that the HSA21- encoded chromatin effector, BRWD1, was upregulated in neurons derived from iPS cells from an individual with Down syndrome and brain of trisomic mice. We showed that selective copy number restoration of Brwd1 in trisomic animals rescued de fi …
