Studies in Amyotrophic Lateral Sclerosis (ALS) and Other Neurodegenerative Motor Neuron Disorders

Recruiting now

Conditions studied: Amyotrophic Lateral Sclerosis

In brief

The purpose of this study is to collect, from patients with sporadic and familial ALS and their family members, clinical data and blood samples for extraction of DNA, RNA, preparation of lymphocytes, plasma and serum to establish a repository for future investigations of genetic contributions to ALS pathogenesis. Blood samples for DNA extraction also would be collected from control subjects with no personal or family history of ALS phenotypes.

• Blood Relative of ALS Patient
• Limited mental capacity rendering the subject unable to provide written informed consent or comply with standard phlebotomy procedures.
• Healthy Control Subject
• Personal or family history of dementia or other neurodegenerative disease (Parkinson disease, Alzheimer disease, etc.);
• Limited mental capacity rendering the subject unable to provide written informed consent or comply with standard phlebotomy procedures.
