TL;DR: The results indicate that there is some genetic overlap between these two phenotypically-related neuropsychiatric disorders, but suggest that the two disorders have distinct genetic architectures.
Journal ArticleDOI

TL;DR: Although no SNPs were identified to be associated with OCD at a genome-wide significant level in the combined trio–case–control sample, a significant enrichment of methylation QTLs and frontal lobe expression quantitative trait loci (eQTLs) was observed within the top-ranked SNPs, suggesting these top signals may have a broad role in gene expression in the brain, and possibly in the etiology of OCD.
