Many physiologic effects of l-glutamate, the major excitatory neurotransmitter in the
mammalian central nervous system, are mediated via signaling by ionotropic glutamate …

Genetic factors play a major part in intellectual disability (ID), but genetic studies have been
complicated for a long time by the extreme clinical and genetic heterogeneity. Recently …

INTRODUCTION Our understanding of the pathophysiology of psychiatric disorders,
including autism spectrum disorder (ASD), schizophrenia (SCZ), and bipolar disorder (BD) …

Background The causes of intellectual disability remain largely unknown because of
extensive clinical and genetic heterogeneity. Methods We evaluated patients with …

Axonal transport is essential for neuronal function, and many neurodevelopmental and
neurodegenerative diseases result from mutations in the axonal transport machinery …

Common diseases are often complex because they are genetically heterogeneous, with
many different genetic defects giving rise to clinically indistinguishable phenotypes. This has …

New mutations have long been known to cause genetic disease, but their true contribution to
the disease burden can only now be determined using family-based whole-genome or …

Epileptic encephalopathies are a devastating group of epilepsies with poor prognosis, of
which the majority are of unknown etiology. We perform targeted massively parallel …

The structure of neuronal circuits that subserve cognitive functions in the brain is shaped
and refined throughout development and into adulthood. Evidence from human and animal …

Autism spectrum disorders comprise a range of neurodevelopmental disorders
characterized by deficits in social interaction and communication, and by repetitive …
