CNTNAP2 and schizoaffective disorder: Furthermore, reduced neural migration was found in forebrain NPCs from schizoaffective disorder patient harboring deletion in CNTNAP2. This phenotype correlated with the exon and allele specific expression patterns of CNTNAP2 in hiPSC-derived NPCs, neurons and oligodendrocyte precursor cells (OPCs) from one patient with CNTNAP2 deletion [75].
