A total of 5220 CNVs were identified from 283 subjects using the conservative CNV detection scheme described above. From these 5220 regions, 253 regions were identified with incidence frequency greater than 1%. The detected CNVs range from 512 bp to 3 × 106 bp with 0.4% greater than 5 × 105 bp in length. A large portion of the CNVs detected occur with frequency less than 1% in the subjects, however here we limit our focus on frequent CNVs (frequency > 1%) to explore the common variant – common disorder hypothesis. Table 3 shows overall statistics for detected CNVs with frequency greater than 1%.
