  1. Continuous variables are summarized with the sample mean ± standard deviation (range). The age provided is age at blood draw in controls, age at onset in clinically diagnosed patients, and age at death in pathologically diagnosed patients. Information was unavailable for age (n = 41) and age at onset (n = 59).
