Deletion mapping by LOH in informative leukemias that have heterozygous proximal and distal breakpoints.

(A) Chromosome 2 (AML) (B) Chromosome 4 (AML and L-ML). Polymorphic microsatellite markers used and their relative genetic positions (cM)20 are shown, as are the number (No.) of AMLs or L-MLs that exhibited a particular LOH pattern (A-O). Solid boxes show regions of LOH.
