Huntington's Disease: A History of Discovery
The history of Huntington's disease stretches across centuries of careful observation, and this page traces that story for general readers.
Long before anyone used the term Huntington's disease, physicians around the world were describing a puzzling movement condition that seemed to run in families.
Understanding the history of Huntington's disease helps us appreciate the researchers, families, and communities who made today's knowledge possible.

Clues in the 1800s
One of the earliest written clues about Huntington's disease appeared in the mid-nineteenth century, when physicians began recording hereditary movement patterns.
An American physician named Charles Oscar Waters wrote about a hereditary form of chorea, an early thread in the history of Huntington's disease.
Doctors on two continents
Around the same time, other clinicians described families with similar movements, adding pieces to the emerging picture of Huntington's disease.
In Norway, a country doctor named Johan Christian Lund also documented affected families, contributing to the early record of Huntington's disease.
These scattered reports did not yet carry a single name, but each one helped build the foundation of what we now call Huntington's disease.
Scholars who study the history of Huntington's disease often point to these early notes as proof that careful observation came long before molecular science.
George Huntington and His 1872 Essay
The condition now called Huntington's disease takes its name from George Huntington, a young American physician who published a concise description in 1872.
George Huntington had observed families near his home on Long Island, and his essay on hereditary chorea became a landmark in Huntington's disease history.
What set George Huntington's account apart was his clear emphasis on the inherited nature of the condition that now bears the name Huntington's disease.
George Huntington also noted how the condition tended to appear in adulthood and to worsen across generations, observations that remain central to Huntington's disease.
1872
The year George Huntington published his influential paper, a date often highlighted in the history of Huntington's disease.
The Name Huntington Spreads
The old term
After George Huntington's 1872 paper, the term hereditary chorea was widely used before the eponym Huntington's disease gradually became standard.
Into the textbooks
Through the late nineteenth and early twentieth centuries, the name Huntington spread through medical literature, teaching, and clinical practice.
Families recognize it
As awareness of Huntington grew, families began to recognize their own experiences in the published accounts of the condition.
The growing use of the name Huntington's disease marked a shift from isolated observations toward a shared understanding among physicians and families alike.
This period in the history of Huntington's disease also saw the first steps toward organized support for affected households.
Progress and Painful Chapters
The twentieth century brought both progress and difficult chapters to the history of Huntington's disease.
Some institutions misused early genetic ideas against people with Huntington's disease, a history that researchers and advocates now openly acknowledge.
In 1968, families and advocates founded an early support organization for Huntington's disease, beginning a new era of community organizing.
Over the following decades, the history of Huntington's disease became as much a story of families as of physicians and laboratories.
Finding the Gene Behind Huntington's Disease
1983: a marker found
A turning point in the history of Huntington's disease came in 1983, when researchers located a genetic marker on chromosome four.
That 1983 finding linked the inheritance of Huntington's disease to a specific region of the genome for the first time.
A global effort
The search for the Huntington's disease gene then became an international effort spanning many laboratories and many dedicated teams.
Families in Venezuela, studied over many years, provided crucial information that advanced the genetics of Huntington's disease.
The decade between the 1983 marker and the identification of the gene is one of the most closely followed periods in the history of Huntington's disease.
The Discovery of the HTT Gene
A collaborative team
In 1993, a collaborative team announced the discovery of the gene responsible for Huntington's disease.
The HTT gene
The 1993 discovery identified the HTT gene and revealed a repeating section of DNA that underlies Huntington's disease.
A defining moment
This milestone transformed the history of Huntington's disease by giving researchers a precise molecular target to study.
The identification of the HTT gene remains one of the most celebrated moments in the history of Huntington's disease research.
News of the discovery gave many families affected by Huntington's disease a renewed sense of hope and a clearer scientific vocabulary.
The CAG Repeat in Huntington's Disease
The HTT gene contains a sequence of three letters, C, A, and G, that repeats a number of times in Huntington's disease.
In Huntington's disease, the number of CAG repeats is often higher than in people who do not have the condition.
Scientists continue to study how the length of the CAG repeat relates to the course of Huntington's disease over a person's lifetime.
This repeating stretch of DNA is the reason Huntington's disease can be traced through families with such clarity.
Families and Advocacy in Huntington's Disease History
Advocacy has been part of the history of Huntington's disease since families first organized to support one another.
Awareness days, community walks, and conferences now connect people affected by Huntington's disease across many countries.
The history of Huntington's disease shows how families turned grief into a movement for education and research.
Community voices remain central to the ongoing story of Huntington's disease and to the push for greater public understanding.
A Timeline of Huntington's Disease History
Physicians on two continents document hereditary chorea, early chapters in the history of Huntington's disease.
George Huntington publishes his landmark essay, giving the condition the name it carries today in discussions of Huntington's disease.
Families establish an early advocacy group, opening a modern chapter in the history of Huntington's disease.
A genetic marker on chromosome four is linked to Huntington's disease, guiding the search that followed.
The HTT gene and its CAG repeat are identified, a defining moment for Huntington's disease research.
Research, education, and awareness continue to grow around Huntington's disease in the United States and worldwide.

Hope
Studying the history of Huntington's disease can inspire patience and hope, even as many questions remain open.
While this page is strictly informational, the history of Huntington's disease is still being written by researchers, families, and communities together.
Frequently Asked Questions About Huntington's Disease History
Who first described Huntington's disease?
Several physicians documented hereditary chorea, but George Huntington's 1872 essay gave the condition the name used today for Huntington's disease.
When was the gene for Huntington's disease found?
A genetic marker was linked to Huntington's disease in 1983, and the HTT gene itself was identified in 1993.
