Children with Down syndrome have a 20- to 50-fold increased risk of acute lymphocytic or myeloid leukaemia. Whole or partial gains of chromosome 21 have been described in multiple childhood leukaemias, and have recently been reported as a likely primary event in B-precursor-acute lymphoblastic leukaemia. It is unclear which amplified gene(s) on chromosome 21 play a key role in leukaemia progression. We describe a minimal amplified segment within the so-called Down syndrome critical region shared between two cases of AML-M0; a Down syndrome, and a constitutionally normal individual. Interestingly, the amplified region does not include the oncogenes RUNX1, ETS2 and ERG

Abstract
Children with Down syndrome have a 20- to 50-fold increased risk of acute lymphocytic or myeloid leukaemia. Whole or partial gains of chromosome 21 have been described in multiple childhood leukaemias, and have recently been reported as a likely primary event in B-precursor-acute lymphoblastic leukaemia. It is unclear which amplified gene(s) on chromosome 21 play a key role in leukaemia progression. We describe a minimal amplified segment within the so-called Down syndrome critical region shared between two cases of AML-M0; a Down syndrome, and a constitutionally normal individual. Interestingly, the amplified region does not include the oncogenes RUNX1, ETS2 and ERGPubblicazioni consigliate
