Abstract

Germ-line genetic control of gene expression occurs via expression quantitative trait loci (eQTLs). We present a large, exon-specific eQTL data set covering ten human brain regions. We found that cis-eQTL signals (within 1 Mb of their target gene) were numerous, and many acted heterogeneously among regions and exons. Co-regulation analysis of shared eQTL signals produced well-defined modules of region-specific co-regulated genes, in contrast to standard coexpression analysis of the same samples. We report cis-eQTL signals for 23.1% of catalogued genome-wide association study hits for adult-onset neurological disorders. The data set is publicly available via public data repositories and via http://www.braineac.org/. Our study increases our understanding of the regulation of gene expression in the human brain and will be of value to others pursuing functional follow-up of disease-associated variants.

  • Genetic variants at the HLA-DQB1 locus discovered in the recent AD genetic meta-analysis included eQTLs for TNXB/TNXA in brain tissues.

    “genetic variants at the HLA-DQB1 locus discovered in the recent AD genetic meta-analysis [84] included eQTLs for TNXB/TNXA in brain tissues [84, 85].”

    From Sex-specific DNA methylation differences in Alzheimer’s disease pathology (2021) · cites this paper as [85]

    The Results section, “Using cis-eQTL signals to interpret GWAS hits” (page not available), reports brain eQTLs for other disease-associated variants, including an Alzheimer’s disease variant regulating CR1. Searches for HLA-DQB1, TNXB, TNXA, and their combination found no passage linking the claimed locus to TNXB/TNXA expression in brain tissue. (LLM, conf=0.74)

  • CommonMind Consortium eQTLs replicate most eQTLs found in other independent samples, with π1 values of 0.98 for GTEx v6, 0.75 for Harvard Brain Bank, 0.70 for BrainCloud, 0.79 for NIH, 0.93 for UKBEC, and 0.77 for HBCC.

    “GTEx v6 is the largest public dataset of eQTLs from DLPFC tissue (n = 92) assayed by RNA-seq; its replication in CMC is π1 = 0.98.”
  • The module memberships were confirmed in the BRAINEAC data for non-Alzheimer's disease control human brains.

    “We confirmed these module memberships in the BRAINEAC data for non-Alzheimer’s disease control human brains generated in our own lab (Ramasamy et al., 2014).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
