Copy number variants (CNVs) at the 16p11.2 chromosomal
locus are associated with several neuropsychiatric
disorders, including autism, schizophrenia, and bipolar
disorder. In this study, we demonstrate widespread and
opposing white matter alterations in pediatric and adult
human carriers of the 16p11.2 deletion versus the
reciprocal duplication. We further show associations of
cognitive and behavioral impairment with deviation in
either direction from normative microstructural white
matter values. These results support the view that
specific genetic variations may be more strongly
associated with changes in brain structure, including
macrostructure and microstructure, than shared
neuropsychiatric diagnoses.
