Complex genetic susceptibility to vascular dementia and an evidence for its underlying genetic factors associated with memory and associative learning

Lee, Chaeyoung, Kim, Younyoung·2013·Gene

Abstract

Genetic basis for vascular dementia (VD) as a typical complex disease has been limitedly reported from association studies conducted with candidate genes. Even recent genomewide association studies (GWAS) could hardly identify additional genetic factors for VD. Although a considerable complexity for its genetic architecture was suspected, there were some challenges to identify false negative associations that resulted from the GWAS. Challenges to identifying genetic factors and their functions after the trials of GWAS revealed that splicing of primary transcript was inhibited (SYK) or delayed (PHLDB2) by a nucleotide substitution of the corresponding gene. The studies gave us the lesson that integrated investigations with statistical genomics as well as functional genomics are needed to identify false negatives from the GWAS. Such endeavors would provide key insights into aspects of underlying nucleotide architectures of VD and incorporate the genetic factors into clinical practice. The recent genetic association studies for susceptibility to VD were briefly overviewed in this article. We also showed a challenge to understanding genetic dissection of VD by a genomic region enrichment analysis with distal cis-regulatory sequences. The analysis with a variant set of potential false negatives from the GWAS revealed that the variants were significantly enriched near genes involved in critical biological processes to VD.

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.
