The field of human genetics has changed dramatically over the last two decades. After years of collaborative work, the human genome sequence was first published in 2001; now, with modern technologies, complete individual genomes can be sequenced for relatively small fees within a matter of days, and we have entered a new era of research on the genetic basis of human variation and disease. The array of accessible sequence data provides us with a vast amount of information on molecular alterations underlying neuropsychiatric disorders, but this step reflects only the first hurdle in the process of developing treatment strategies that benefit patients. The next critical step – understanding disease mechanism – is the bottleneck in the translational process. This area is the focus of our work. Genetic studies have highlighted that numerous transmembrane receptors, cell adhesion molecules, and multiple scaffolding proteins at the postsynaptic density (PSD) have been implicated in autism and related developmental disorders, highlighting this structure as an obvious target for detailed study. In my lab, we combine genetic and pharmacological approaches with advanced image analysis techniques to explore molecular events that potentially influence the formation and function of synapses and the generation of functional neuronal networks.
