The Collaborative Center for XDP invites applicants to submit letters of intent for the 2019 Research Funding Program.


The Collaborative Center for X-Linked Dystonia-Parkinsonism (CCXDP) supports an international consortium of scientists, clinicians, and patient advocates working together to advance research and treatments for X-Linked Dystonia-Parkinsonism (XDP), a debilitating neurodegenerative disease. CCXDP is now seeking applications for its 2019 Research Funding Program.  Three grant mechanisms are offered:

  • Investigator Awards:                   2 years, up to $250,000/year in direct costs.
  • Exploratory Pilot Grants:            1 year, up to $100,000 in direct costs
  • Postdoctoral fellowships:           2 years, $75,000/year in direct cost.

In addition to the amounts listed above, awards will provide 10% indirect costs to recipient institutions. 


XDP is a neurodegenerative disorder endemic to the Philippines. Recent CCXDP-funded research studies have shown that XDP is most likely caused by a disease-specific SINE-VNTR-Alu (SVA)-type retrotransposon insertion in an intron of the human TAF1 gene.  The SVA contains a hexameric sequence (CCCTCT)n, the length of which is polymorphic among patients and inversely correlated to age of disease onset.  The insertion results in aberrant TAF1 mRNA splicing and partial intron retention which decreases levels of the full-length transcript.  The neuropathology of XDP has not yet been fully defined, but previous studies have reported a progressive loss of striatal medium spiny neurons in the brains of individuals with XDP.

Available Resources

CCXDP has generated biospecimens and reagents which are available for research studies, including:

  • DNA from XDP patients and unaffected relatives
  • Fibroblasts, lymphoblasts, and induced pluripotent stem cells (iPSCs) from XDP patients and unaffected relatives
  • Post-mortem human brain tissue from XDP patients
  • Novel TAF1 antibodies

Research Objectives for the 2019 Funding Program

CCXDP welcomes applications from investigators in all disciplines proposing bold and rigorous approaches to the study of XDP. We encourage proposals involving collaborative studies, which can include investigators at different institutions, as well as ones which leverage existing resources. Areas of particular interest include, but are not limited to:

  • Characterization of SVA retrotransposon dynamics in XDP cells/tissue
  • Splicing regulation, RNA processing and/or RNA structure in XDP cells/tissue
  • Proteomic profiling of XDP and control cells/tissue
  • Development of assays to screen for modifiers of XDP cellular phenotypes
  • Development of novel iPSC-based models, including cerebral organoids and/or human neural progenitors implanted into rodent brain.
