Project description:SNP profiling can reveal copy number abnormalities and loss of heterozygosity associated with distinct biologic subtypes of acute lymphoblastic leukemia (ALL). We performed SNP profiling of Down syndrome ALL cases and controls to identify unique biologic features of this ALL subgroup.
Project description:SNP profiling can reveal copy number abnormalities and loss of heterozygosity associated with distinct biologic subtypes of acute lymphoblastic leukemia (ALL). We performed SNP profiling of Down syndrome ALL cases and controls to identify unique biologic features of this ALL subgroup. Ficoll-enriched, cryopreserved bone marrow aspirate samples were obtained from patients with B-precursor ALL at diagnosis and in remission; and from control patients without leukemia.
Project description:Gene expression profiling (GEP) can reveal characteristic signatures associated with distinct biologic subtypes of acute lymphoblastic leukemia (ALL). We performed GEP on Down syndrome (DS) and comparison non-Down syndrome (NDS) ALL cases to identify biologic differences between these groups. Ficoll-enriched, cryopreserved diagnostic bone marrow samples were obtained from patients with newly diagnosed B-precursor acute lymphoblastic leukemia.

We performed GEP on Down syndrome (DS) and comparison non-Down syndrome (NDS) ALL cases to identify biologic differences between these groups.
Project description:Methylation profiling can reveal patterns of hypermethlation and hypomethylation associated with distinct biologic subtypes of acute lymphoblastic leukemia (ALL). We performed methylation profiling of Down syndrome ALL cases and controls to identify unique biologic features of this ALL subgroup.
