Abstract:
Cytogenetic analysis of bone marrow cells demonstrated a pericentric inversion of chromosome 6 when acute myeloblastic leukemia (AML) was diagnosed in a 15-month-old child with Down syndrome. The abnormal clone with inv(6)(p24q16) was associated with FAB-M1 AML and disappeared when a complete remission was achieved. This is a unique cytogenetic abnormality for FAB-M1 AML in a child with Down syndrome and, to our knowledge, is only the second case of a pericentric inversion of chromosome 6 reported in AML.
