Recommendations for the management of the haematological and onco-haematological aspects of Gaucher disease.

Current knowledge of the haematological and onco-haematological complications of type 1 Gaucher disease has been reviewed with the aim of identifying best clinical practice for treatment and disease management. It was concluded that: (i) Awareness of typical patterns of cytopenia can help clinicians distinguish haematological co-morbidities. (ii) Red blood cell studies and complete iron metabolism evaluation at baseline are recommended.

Translocation (X;12)(p11;p13) as a sole abnormality in biphenotypic acute leukemia.

A reciprocal t(X;12)(p11;p13) was found as the sole clonal abnormality in biphenotypic leukemia with myeloid and B-lymphoid differentiation. With fluorescence in situ hybridization analysis, the ETV6 gene (previously TEL) was found to be translocated intact to the derivative X chromosome; no MLL and BCR/ABL rearrangements were found. The patient achieved complete remission after induction chemotherapy.
