Pedigree of the family under study with FPD-AML. The arrow identifies the proband (III-2). The FPD phenotype is shown in black. The STRP studied are shown here and cosegregation of linked haplotypes in family members with FPD is shown in the shaded box. II-2 developed AML and was posttransplantation when DNA samples were collected so that her analysis was inferred and shown in parenthesis. Five other flanking markers were genotyped and had negative lod scores. For clarity, these data are not shown.
