HD Human Biology Project Overview

Despite the identification of the gene responsible for Huntington’s disease (HD) over 25 years ago, to date there are no effective treatments available to patients to modify disease progression. Although animal models have been instrumental to our understanding of HD biology, the most physiologically relevant scientific observations are those that are recorded in humans with HD. As a result, the Huntington’s Disease Society of America has adopted a patient-centric research strategy to push the field closer to meeting our goal of identifying effective therapies. The HD Human Biology Project is the cornerstone of this strategy. To date, HDSA has committed more than $7 million dollars to support this program!

The Human Biology Project was launched in 2013 with the goal of fostering innovative research in collaboration with HD clinics to better understand the biology of Huntington’s disease as it occurs in humans. HDSA encourages researchers to consider one of HDSA’s Centers of Excellence as a potential collaborator, but applicants may propose to work with any HD clinic around the world.

Project Details

  • 1-2 years of funding to support a scientist working collaboratively with an HD clinic anywhere in the world
  • Awards up to $75,000/year ($50,000 salary support and $25,000 research budget)
  • Recipient must commit at least 50% effort to the project
  • Open to researchers from around the world regardless of position/title
  • Preference given to young postdoctoral and clinical investigators (PhD and/or MDs) who are not yet independent
  • Innovative ideas from non-scientists will also be accepted and encouraged
  • Applications from for-profit institutions are welcome

Request for Proposals

This document outlines for researchers the full award details, important dates and deadlines, eligibility, and financial information for the HDSA Human Biology Project. The 2023 RFP is available for download here. 

Letter of Intent

All interested applicants must provide administrative information and upload a completed Letter of Intent (LOI) via our online application system, ProposalCentral.

If you have previously used ProposalCentral, you may sign in here and search for an Open Opportunity by typing “Huntington’s Disease Society of America” in the search box field and filtering opportunities by Grant Maker. This should take you to the Human Biology Project LOI. If you have not used ProposalCentral before, you can create an account using the same link.   

You can also begin a new application by following this direct link: https://proposalcentral.com/ProposalGI.asp?SectionID=12065&ProposalID=-1 

The LOI should be a short Microsoft Word document, maximum 2 pages, including the following information:

  • A short summary that outlines the intended research and specifically states how the results will help us better understand the biology of HD as it occurs in humans.
  • Any background and/or preliminary data
  • Specific aims
  • Brief experimental plan, including time required to complete studies
  • Qualifications of the researcher/applicant

Applicants whose LOIs have been accepted will be notified by email within 2 weeks of the submission deadline and will be provided the full application via our online system.


The full application requires administrative information, a signature from the applicant and their organization acknowledging the terms and conditions of this award, biographical sketches and a list of other funding (can be NIH-style) for the applicant, mentor, and other key personnel listed in the budget, a scientific abstract, lay description, and research proposal, 1-3 letters of reference from mentors or clinical collaborators, and institutional approvals for any human or animal work.   

Summaries of previously funded projects can be found below.
