Epigenome-wide association study of suicide attempt in schizophrenia

In this study, epigenome-wide patterns of methylation were measured in schizophrenia suicide attempters (n = 54) and schizophrenia non-suicide attempters (n = 69) using DNA extracted from white blood cells (WBC). Analyses focused on identifying differentially methylated CpG sites and gene regions between the attempters and non-attempters. We identified the CpG site cg19647197 within the CCDC53 gene, which is characterized by hypomethylation of WBC in the attempters compared to the non-attempters. Our results suggest that there is variation in DNA methylation associated with suicide attempt that may offer novel highlights into the molecular mechanisms linked to suicide attempt associated with schizophrenia.
