The columns of the table denote the Illumina array types. The column “Lab” denotes the laboratory that performed the genotyping: BU = Boston University; CIDR = Center for Inherited Disease Research. The row Illumina I denotes the control samples included in the discovery set; Illumina II denotes the control samples included in the first replication set, and Illumina III denotes the residual samples from the Illumina repository; Coriell NINDs denotes the neurologically normal controls.
