Abstract

Here, we perform a genome-wide screen for variants that regulate the expression of gene co-expression modules in the aging human brain; we discover and replicate such variants in the TMEM106B and RBFOX1 loci. The TMEM106B haplotype is known to influence the accumulation of TAR DNA-binding protein 43 kDa (TDP-43) proteinopathy, and the haplotype's large-scale transcriptomic effects include the dysregulation of lysosomal genes and alterations in synaptic gene splicing that are also seen in the pathophysiology of TDP-43 proteinopathy. Further, a variant near GRN, another TDP-43 proteinopathy susceptibility gene, shows concordant effects with the TMEM106B haplotype. Leveraging neuropathology data from the same participants, we also show that TMEM106B and APOE-amyloid-β effects converge to alter myelination and lysosomal gene expression, which then contributes to TDP-43 accumulation. These results advance our mechanistic understanding of the TMEM106B TDP-43 risk haplotype and uncover a transcriptional program that mediates the converging effects of APOE-amyloid-β and TMEM106B on TDP-43 aggregation in older adults.

  • Both GRN and TMEM106B have already been associated with neuropathological features of AD.

    “Lastly, both GRN and TMEM106B have already been associated with neuropathological features of AD46–48.”

    From New insights into the genetic etiology of Alzheimer’s disease and related dementias (2022) · cites this paper as [48]

    The Results section on the GRN locus links both GRN and TMEM106B to TDP-43 proteinopathy. The Discussion places both in a proposed model of LATE-NC pathogenesis that is also exacerbated by amyloid-β accumulation. The paper does not establish that both genes are associated with AD neuropathological features themselves; it chiefly describes TDP-43 pathology and a pathway connecting AD and LATE-NC (page numbers unavailable).

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.
