Array-MLPA analysis of normal controls (15 normal females and 15 normal males). The average copy numbers on chromosomes 13, 18, 21, X and Y were shown in A, B, C, D and E, respectively. The normal distributions of copy number in the control individuals were shown with two grey lines. Error bars represented the corresponding standard deviation (SD) of the copy numbers for the MLPA probes covering each chromosome.
