CONTEXT Results of comparative genomic hybridization studies have suggested that rare copy number variations (CNVs) at numerous loci are involved in the cause of mental retardation, autism spectrum disorders, and schizophrenia. OBJECTIVES To provide an estimate of the collective frequency of a set of recurrent or overlapping CNVs in 3 different groups of(More)
Parkinson's Disease (PD) is characterized by a selective loss of nigrostriatal dopaminergic neurons that results in a marked reduction of dopaminergic nerve terminals in the striatum. Recently, 11C-WIN 35,428, a cocaine analogue that specifically labels the dopamine transporter, was developed and can be used to label dopaminergic nerve terminals in vivo by(More)
Autism spectrum disorder (ASD) is a serious childhood-onset disorder in which social and language development are primarily affected, with associated repetitive behavior and, in some patients, behavioral symptoms including aggression and self-injury. In ASD, risperidone and aripiprazole are the only second-generation antipsychotic drugs that have shown to(More)
Semaphorins are a large family of secreted and membrane-associated proteins necessary for wiring of the brain. Semaphorin 5A (SEMA5A) acts as a bifunctional guidance cue, exerting both attractive and inhibitory effects on developing axons. Previous studies have suggested that SEMA5A could be a susceptibility gene for autism spectrum disorders (ASDs). We(More)
