英文摘要
Project Summary
This application proposes the Washington University in St. Louis School of Medicine (WUSM) Model Organism
Screening Core (wuMOSC) as a key asset for Phase II of the NIH Undiagnosed Diseases Network (UDN). The
wuMOSC will evaluate the pathogenicity of 200 genetic variants per year identified by UDN Clinical Sites in
otherwise undiagnosed participants by leveraging the optimal combination of the following four animal model
organisms and human cell-based Resource Cores: 1) C. elegans, 2) Drosophila, 3) zebrafish, and 4) human
pluripotent stem cells (hPSCs). This multi-organism approach capitalizes on the experimental advantages of
these four model systems, while avoiding the limitations of individual models. Extending the established
advantages of the Drosophila and zebrafish, C. elegans allows for extremely rapid and cost-effective variant
evaluation, while hPSCs enable assessment of genes and variants that are not conserved in animal models.
An experienced Leadership Team has been assembled that harnesses the collaborative research environment
at WUSM, including the expertise of the McDonnell Genome Institute, and the superb WUSM clinical partners
that constitute the proposed UDN Phase II WUSM Sequencing Center and Clinical Site applications,
respectively. Using proven, cutting-edge, and novel bioinformatic approaches, combined with thoughtful
consideration of the advantages and limitations of each model organism, a careful assessment plan has been
defined for determining the putative pathogenicity of nominated variants and prioritizing them for experimental
evaluation by the Resource Cores. Preliminary data demonstrate that all four Resource Cores are using
efficient and advanced genetic targeting techniques, including CRISPR/Cas9 to knock-in the human variant
into an orthologous gene, knock-down and loss-of-function assays where appropriate, and overexpression to
assess rescue of loss-of-function or for gain-of-function. Phenotypic analysis of the genetic models will be
guided by information in model organism databases and the literature, as well as patient symptoms. This
information will then be applied to the organism-specific and extensive phenotyping pipelines. The UDN
Clinical Sites, Steering Committee, and Coordinating Committee will receive frequent communications
regarding plans and results of the wuMOSC, through the activity of the Administrative Core, which will also
disseminate acquired model organism expertise to the wider NIH and other research communities. Therefore,
the multi-model organism wuMOSC will have an exceptionally high impact on the diagnostic efforts of the UDN
by bioinformatically and experimentally evaluating the potential of disease-causing variants in the context of
disease-specific phenotypes.
