Genetics Study

Tremor researchers at Yale University in New Haven, Connecticut are gearing up to conduct a study of the genetics of essential tremor and they are in need of help from the ET community. If you are from an ET family and meet ALL of the following 5 criteria, then please contact the Yale University researchers at or call 203.785.6599. Please include your contact information (email address, telephone number and full mailing address).


  1. You yourself have ET that was diagnosed by a doctor and you do not have any accompanying dystonia or Parkinson’s disease.
  2. Your tremor had started by the time you were 40 years of age.
  3. You have at least two relatives who have ET also diagnosed by a doctor. They also do not have any accompanying dystonia or Parkinson’s disease.
  4. The two relatives are both living (not deceased) and are first-degree relatives (siblings, parents, children) rather than second-degree relatives (grandparents, grandchildren, aunts/uncles, nieces/nephews).
  5. You think you and your affected relatives would be interested in donating a blood sample to the researchers.

You and your relatives may live anywhere in the United States and still qualify to participate; researchers would travel to you.
