Sizes and types of chromosome 22 deletions. The diagram summarizes the deletions identified in the 80 participants of the study. Diamond regions indicate a hemizygous deletion of one gene copy; solid dark regions indicate the presence of two copies of chromosome 22; solid light regions indicate uncertain areas of deletion. Locations of assays in base pairs are noted (as reported in the UCSC Genome Browser, 2013). Numbers of individuals are noted on the left. Genes in black indicate TaqMan assays and genes in red indicate EvaGreen assays.
