Fig. 2From: Implications of copy number variation in people with chromosomal abnormalities: potential for greater variation in copy number state may contribute to variability of phenotypeCopy number variation on chromosome 21. This shows the penetrance plot of aberration calls on chromosome 21 from array CGH data from 50 apparently healthy French Caucasian males (de Smith et al.2007), generated using ADM-2 algorithm with threshold 4 in CGH Analytics 3.4. This displays the percentage of the 50 arrays that have an aberration at each probe position along the chromosome: deletion aberrations point downwards from 0, and amplifications point upwards. The box shows the position of the CNV within DSCAMBack to article page
