Who this trial is looking for
This trial is looking for people with early-onset parkinsonism to discover genetic causes. Participants will provide samples and help researchers understand the genetics of the disease.
Are You a Good Fit for This Trial?
You may be able to join if
I have symptoms of parkinsonism that started before age 40
I have a family history of parkinsonism
I have a brain scan that shows dopaminergic denervation
DNA samples from both my asymptomatic parents are available
I have health insurance
I can understand the research and give my consent
You may not be able to join if
I cannot have a skin biopsy
I already know the genetic cause of my parkinsonism
I have not had previous genetic testing for this condition
I have late-onset parkinsonism starting after age 40 without family history
I have parkinsonism linked to a specific diagnosis like toxic exposure
I cannot receive the necessary information about the study
I am under judicial protection
I am under guardianship or curatorship

Despite the increasing availability and advances in the analysis of high-throughput DNA sequencing, the majority of patients with early-onset or familial parkinsonism remain without a molecular diagnosis.
Studying the genetic forms of parkinsonian syndromes presents numerous clinical, scientific and therapeutic interests. In clinical practice, identifying the genetic cause in a patient allow to provide genetic counseling and estimate the risk of recurrence in their relatives. Establishing correlations between the genotype and phenotype of patients with genetically determined parkinsonism, allow to better anticipate the evolution of the disease, or even to highlight biomarkers during the presymptomatic phases. Finally, the proteins encoded by the genes implicated in familial parkinsonism represent potential therapeutic targets likely to be modulated by neuroprotective pharmacological agents, even in sporadic Parkinson's disease.
In this work,investigators aimed at elucidating the missing genetic causes of parkinsonism through the application of combined RNA and whole genome sequencing.
