Cellular and molecular studies on infant null acute lymphoblastic leukemia

Cellular and molecular studies on infant null acute lymphoblastic leukemia.

We have studied the cellular and molecular basis of eight cases of infant null acute lymphoblastic leukemia (ALL). All eight patients were under 9 months of age and presented with leukocyte counts in excess of 60 X 10(9)/L, organomegaly, and in two cases CNS infiltration. Although seven cases were morphologically classified as ALL, one patient had both lymphoid and myeloid features. Phenotypic ...

Infant Acute Lymphoblastic Leukemia

Acute lymphoblastic leukemia (ALL) in infants under 12 months of age accounts for about 4% of childhood ALL and differs from ALL in older children with respect to immunophenotypic, cytogenetic and molecular genetic features. In contrast to the predominance of male sex in older children with ALL, there is a slight predominance of girls in infant ALL (1). In infant leukemia, all necessary genetic...

Molecular genetics of acute lymphoblastic leukemia.

From its beginnings two decades ago with the analysis of chromosomal translocation breakpoints, research into the molecular pathogenesis of acute lymphoblastic leukemia (ALL) has now progressed to the large-scale resequencing of candidate oncogenes and tumor suppressor genes in the genomes of ALL cases blocked at various developmental stages within the B- and T-cell lineages. In this review, we...
