Fanconi anaemia (FA) is an inherited disease with congenital and developmental 
abnormalities, bone marrow failure, and extreme risk of leukemic transformation. 
Bone marrow surveillance is an important part of the clinical management of FA 
and often reveals cytogenetic aberrations. Here, we review bone marrow findings 
in FA and discuss the clinical and biological implications of chromosomal 
aberrations associated with leukemic transformation.
