Distributions of repeat number in C9orf72 in Alzheimer's disease, Parkinson disease, essential tremor, and control individuals. There was no significant difference in the distributions of repeat length between AD (p = 0.67), ET (p = 0.13) cases and controls, respectively. However, an evidence of significant distribution was identified between PD cases and controls (p = 0.01); 17+ in PD patients including five PD cases at 18, 19, 22, 23, 27 repeats.
