In this study, we performed a meta-analysis to characterize disease-associated regulatory modules by performing single-cell transcriptome analysis of developing neurons from reciprocal human ESC models of CNV in the distal 1q21.1 region. As a result, we observed significant directional enrichment of a series of genes in neuronal cells associated with autism spectrum disorder (ASD), bipolar disorder, and schizophrenia. Correlation analyses revealed that the disease-associated signature primarily targeted epigenetic regulatory mechanisms. We also identified Bromodomain PHD Finger Transcription Factor (BPTF), a key component of the NURF chromatin remodeling complex, as a potential target responsible for transcriptome changes related to human neuropsychiatric diseases, including ASD. We provide a practical and straightforward analytical workflow for utilizing both public data and in-house single-cell omics data from disease models.
