in the UK. The aim of the study is to identify new genes that predispose or cause Parkinson's Disease or Parkinsonism. There is a pressing need to study the genetic makeup of family members both with and without Parkinson's. As families share a common genetic background, it is easier to find new Parkinson's genes by studying the genetic makeup of people with Parkinson's alongside other members of their families. We are particularly interested in studying the genetic makeup of two groups of people:
1. those who developed Parkinson's before the age of 45; and
2. those who have a family history of other relatives affected by Parkinson's.
By identifying genetic factors that cause Parkinson's, we hope to understand more about the condition. Doing so will lead to the development of better diagnosis, improved disease models, and we hope in time, to the development of better treatment.
