We profiled sporadic and LRRK2 positive patients and produced powerful models with an AUC of 0.88 (sensitivity = 1; specificity = 0.75) for diagnosing sPD and a model with an AUC = 0.94 (sensitivity = 0.88; specificity = 1) for diagnosing LRRK2 PD patients (Supplementary Table S8). The gene discussed is LRRK2; the disease is Parkinson disease.
