Targeted sequencing of genes in the 16p11.2 interval was performed in all carriers of the 16p11.2 microdeletion, and whole\u2010genome expression profiling analysis was performed for the patient carriers and normal carriers in their intra\u2010family.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Three patients carrying the 16p11.2 microdeletion were screened out, indicating a frequency of 0.33% for the 16p11.2 microdeletion in this cohort. We reviewed the neurodevelopmental trajectories of the 16p11.2 microdeletion carriers from childhood to puberty and confirmed that this microdeletion was associated with abnormal neurodevelopment, with varied neurodevelopmental phenotypes. A differential <jats:italic>PRRT2<\/jats:italic> genotype (rs10204, T&gt;C) was identified between patients and normal carriers of the 16p11.2 microdeletion. Moreover, the determination of differential whole\u2010genome expression profiling demonstrated the destruction of the top\u2010ranked network in neurogenesis and accounted for observation of abnormal
