Trisomy 21, or Down syndrome (DS), is the most common genetic cause of
developmental delay and intellectual disability. To gain insight into the
underlying molecular and cellular pathogenesis, we conducted a multi-region
transcriptome analysis of DS and euploid control brains spanning from mid-fetal
development to adulthood. We found genome-wide alterations in the expression of a
large number of genes, many of which exhibited temporal and spatial specificity
and were associated with distinct biological processes. In particular, we
uncovered co-dysregulation of genes associated with oligodendrocyte
differentiation and myelination that were validated via cross-species comparison
to Ts65Dn trisomy mice. Furthermore, we show that hypomyelination present in
Ts65Dn mice is in part due to cell-autonomous effects of trisomy on
oligodendrocyte differentiation and results in slower neocortical action
potential transmission. Together, these results identify defects in white matter
development and function in DS, and they provide a transcriptional framework for
further investigating DS neuropathogenesis.
