摘要: Schizophrenia genome-wide association (GWA) studies have identified over 150 regions of the genome that are associated with disease risk, yet there is little evidence coding mutations contribute to this disorder. To explore mechanism non-coding regulatory elements in schizophrenia, we performed ATAC-seq on adult prefrontal cortex brain samples from 135 individuals schizophrenia and 137 controls, 118,152 peaks. These accessible chromatin highly enriched for SNP-heritability (10.6 fold enrichment, P=2.4x10-4, second only genomic conserved Eutherian mammals) replicated an independent dataset (9.0 P=2.7x10-4). This degree enrichment heritability was higher than open found 138 different cell tissue types. Brain overlapped exhibited even indicating conservation can identify functional subsets within active brain. However, did not accessibility differences between cases nor find interaction QTLs case-control status. indicates although causal variants map elements, mechanisms other differential may govern contribution element variation risk. Our results strongly implicate gene processes involving pathogenesis suggest a strategy understand hundreds common emerging large complex diseases.
