Genetic Study of Familial and Sporadic ALS/Motor Neuron Disease, Miyoshi Myopathy and Other Neuromuscular Disorders

Participants will be asked to provide a blood sample ( or sometimes saliva or skin sample) and to complete a couple of questionnaires regarding their overall medical health. Medical records will need to be reviewed for all those diagnosed with one of the study diseases to allow the researchers to review details of their clinical disease symptoms, neurological exams and test results. Participants do not need to travel to Massachusetts for this study. Samples can be obtained locally at no costs to the participant. Family members may be included in the study depending on family history and their relationship to the affected individual.
