______

UPN and breakpoint sequences are given for each patient. Mini-direct-repeats are underlined; Filler-DNA is shown in bold (Filler DNA = sequences not derived from chromosome 11 or 19); for patient P04-324, a 848 bp insertion was identified at the breakpoint that derived from the GNA15 gene located about 3.1 Mbp telomeric to the MLLT1 gene at chromosome 19p13.3. Chromosome 19 sequences are shown in italics.
