title: A simple diagnostic test for Fanconi anemia by flow cytometry.
abstract: A simple diagnostic test for Fanconi anemia (FA) by flow cytometry is proposed. It is based on the cell cycle disturbances of FA cells and their sensitisation by alkylating agents. Following PHA-stimulation of whole blood cell cultures in the presence or absence of nitrogen mustard, the accumulation of cells in G2/M phase was measured. A sharp increase of cells in G2/M was observed in cultures from FA patients when nitrogen mustard was added. This increase allows one to distinguish FA patients from patients with anemias of other origin, healthy controls, and FA heterozygotes, as effectively as chromosome breakage studies. The rapidity of the test and its reliability as demonstrated on the ten FA patients studied, will make the diagnosis of FA easier in centers without cytogenetic laboratory facilities.
