Evidence of neurocognitive and resting state functional connectivity differences in carriers of NRXN1 deletions.

ABSTRACT:

Background

NRXN1 deletion (NRXN1 del) is a rare copy number variant associated with several neurodevelopmental, neuropsychiatric, and cognitive outcomes. The NRXN1 gene encodes for a pre-synaptic cell adhesion molecule that is important for synapse formation, regulation and neurotransmission. We used a gene-first approach to investigate neurocognitive and brain phenotypes in NRXN1 del carriers.

Methods

Forty-two participants (21 NRXN1 del carriers and 21 neurotypical age and sex-matched comparisons) completed IQ assessments, and a neurocognitive battery, including, executive function, attention, and social cognition tasks. Magnetic resonance imaging (MRI) data, including T1-weighted anatomical scans, resting state functional MRI and diffusion tensor imaging, were acquired in
