BACKGROUND Deletion of the recurrent ~600 kb BP4-BP5 chromosomal region 16p11.2 has been associated with a wide range of neurodevelopmental outcomes. METHODS To clarify the phenotype of 16p11.2 deletion, we examined the psychiatric and developmental presentation of predominantly clinically referred individuals, with a particular emphasis on broader autism(More)
IMPORTANCE The 16p11.2 BP4-BP5 duplication is the copy number variant most frequently associated with autism spectrum disorder (ASD), schizophrenia, and comorbidities such as decreased body mass index (BMI). OBJECTIVES To characterize the effects of the 16p11.2 duplication on cognitive, behavioral, medical, and anthropometric traits and to understand the(More)
BACKGROUND Deletions and duplications of the 16p11.2 BP4-BP5 locus are prevalent copy number variations (CNVs), highly associated with autism spectrum disorder and schizophrenia. Beyond language and global cognition, neuropsychological assessments of these two CNVs have not yet been reported. METHODS This study investigates the relationship between the(More)
Chromosome 16p11.2 deletions and duplications are among the most frequent genetic etiologies of autism spectrum disorder (ASD) and other neurodevelopmental disorders, but detailed descriptions of their neurologic phenotypes have not yet been completed. We utilized standardized examination and history methods to characterize a neurologic phenotype in 136(More)
The 16p11.2 duplication (BP4-BP5) is associated with Autism Spectrum Disorder (ASD), although significant heterogeneity exists. Quantitative ASD, behavioral and neuropsychological measures and DSM-IV diagnoses in child and adult carriers were compared with familial non-carrier controls, and to published results from deletion carriers. The 16p11.2(More)
