| Abstract: |
Forty-one families with multiple cases of de novo acute myeloid leukemia (AML), B-cell acute lymphocytic leukemia (B-ALL), or both are presented. The families were randomly collected from physicians, genetic counselors, and other sources. Medical records were collected and reviewed for all families. In 17 of the families, a parent and child with acute leukemia were identified; and in 15 of the pairs, the parent and child were of the same sex. Nine grandparent–grandchild affected pairs with AML-AML were identified, occurring in six families, and six of those pairs were also of the same sex. Anticipation was a common feature of these multigenerational pairs. Twenty families were identified with multiple siblings (none twins) with acute leukemia. This includes 16 sibling pairs and 4 sibling triples. The members of each sibling pair in the AML-AML group and in the B-ALL-B-ALL group were generally of roughly the same age. Curiously, this is not true of those in the AML-B-ALL group. Four of the 41 families had contributions to more than 1 family relationship category. Although inheritance in familial acute leukemia has usually been consistent with an autosomal dominant pattern, these data suggest that an X chromosome gene may be involved in some cases, perhaps in the pseudoautosomal region of the X chromosome as we have reported in familial Hodgkin lymphoma.
