Pattern of allelic imbalances in gastric MZBCL of MALT type and their relationship to the t(11;18).

Chromosomal regions analyzed are shown at the top of each column. Patients are listed in the first column with their t(11;18) status as detected by FISH (ND = not done) or RT-PCR (NA = no amplificate) given in the second and third columns, respectively. Status of each locus is indicated: (▤), retention of heterozygosity; (▧), not informative; (▥), no amplificate; (□), genomic DNA amplification; and (■), LOH.
