Nuclear SLIC-CAGE of human cortical neurons from Cornelia de Lange Syndrome patients and control individuals

We used SLIC-CAGE to map transcriptional start sites in cortical neurons from Cornelia de Lange Syndrome (CdLS) patients and control individuals. SLIC-CAGE was performed using nuclear RNA isolated from pre-frontal cortical grey matter. Usage of nuclear RNA allows enrichment of unstable RNAs, such as RNA originating from enhancer transcription. We characterised promoter-level gene expression in cortical neurons from CdLS patients and found deregulation of hundreds of genes enriched for neuronal functions.
