  1. aMinimum region of overlap across all subjects harboring the deletion.
  2. bCNV frequencies are derived from SNP microarray data.
  3. cAlgorithm detected CNVs were all validated by RT-qPCR with the exception of one case in each of the chromosome 13 and 16 regions due to unavailable DNA. Furthermore, RT-qPCR identified a heterozygous deletion in one case and two control subjects in the chromosome 16 CNV region as well as a case subject in the chromosome 19 region that were called as copy normal by the algorithms.
  4. dWhite female subjects from a GWAS of schizophrenia genotyped using Affymetrix SNP 6.0 microarrays. CNVs were detected using the same algorithms as the PE GWAS. Four population-based controls did not pass sample QC.
