ABSTRACT
We report a new case of transient myeloproliferative disorder (TMD) in a non Down syndrome neonate. The cytogenetic and molecular studies within from the blood blast cells identified a trisomy 21 and a partial deletion in exon 2 of the transcription factor GATA1. Spontaneous regression of the TMD was achieved at the age of 1 month as the clonal and molecular abnormalities. A survey by periodic cytological examinations of peripheral blood cells and GATA1 mutation analysis was instituted since three years and has not detected up to date acute leukaemia.
