DS occurs in one out of every 691 live births and is the most common genetic cause of intellectual disability, affecting approximately 400,000 Americans. The underlying developmental and genetic causes of this intellectual disability in DS are not fully known and because of this lack of knowledge, no treatment is currently available.

The findings, which appear in the journal Neuron, could lead to possible therapies for…
