a The frequency of deletion and duplication in patients with 22q11.2 imbalance undergoing multiplex ligation-dependent probe amplification (MLPA) P245 analysis. b The frequency of abnormal probes detected by P245 assay. Y-axis represents number of patients. c The frequency of different levels of 22q11.2 deletions. d The frequency of different levels of 22q11.2 duplications. LCR, low copy repeats
