## Abstract High hyperdiploidy (51β67 chromosomes) is the most common cytogenetic abnormality pattern in childhood Bβcell precursor acute lymphoblastic leukemia (ALL), occurring in 25β30% of such cases. High hyperdiploid ALL is characterized cytogenetically by a nonrandom gain of chromosomes X, 4,

## Abstract The functional consequences of a highβhyperdiploid karyotype, found in up to oneβthird of cases of acute lymphoblastic leukemia (ALL), are unknown. Using the technique of comparative expressed sequence hybridization (CESH), we sought to address the question of whether increased chromoso
## Abstract Although it has been suggested that mutations of the __FLT3__, __NRAS__, __KRAS__, and __PTPN11__ genes are particularly frequent in high hyperdiploid (>50 chromosomes) pediatric acute lymphoblastic leukemias (ALLs), this has as yet not been confirmed in a large patient cohort. Furtherm
