Analysis of an AGS patient. (A) Flow cytometry plot from whole peripheral blood of an AGS patient showing (left) forward-sideward scatter and (right) CD19 PE/CD5 APC scatter gated on lymphoid cells. (B) Whole genome array of chromosome 20 from leukemia cells of an AGS patient, visualized in Nexus (BioDiscovery). The log2 ratio indicates copy number changes, and the B-allele frequency plot indicates loss of heterozygosity.
