Sammanfattning : The t(12;21) translocation generates the ETV6/RUNX1 fusion gene, present in 25% of childhood acute lymphoblastic leukemia. This fusion gene is important for leukemia development but is not sufficient for leukemia to arise. LÄS MER
Sammanfattning : Mental retardation (MR) is characterised by significant limitations in intellectual function and adaptive behaviour. It is estimated that MR affects up to 3% of the population in Europe. Patients with MR are an aetiologically heterogeneous group. Approximately 25-35% of the patients have a genetic diagnosis.

Sammanfattning : The focus of this thesis was to study cytogenetic and molecular genetic aberrations in lipomas. For this purpose, chromosome banding analysis, fluorescence in situ hybridization (FISH), as well as high resolution single nucleotide polymorphism (SNP)–arrays were used to identify recurrent chromosomal aberrations in lipomas.

Sammanfattning : Soft tissue tumors (STT) constitute a heterogeneous group of tumors that arise in tissues of mesenchymal origin. They are currently classified according to morphology and resemblance to normal tissue into over 100 subtypes. LÄS MER
5. Genetic and epigenetic characterization of pediatric high hyperdiploid acute lymphoblastic leukemia
Sammanfattning : The aim of this thesis was to analyze the genetic and epigenetic characteristics of pediatric high hyperdiploid acute lymphoblastic leukemia (HeH ALL), the most common type of childhood malignancy. The three original articles presented in this thesis have addressed three major questions regarding HeH ALL: what are the genetic characteristics of the most common structural abnormality – dup(1q)? Are aberrant methylation patterns involved in leukemogenesis? How do diagnostic and relapse samples relate to each other genetically? In article I we found that the proximal breakpoints of dup(1q)-positive Burkitt lymphomas (BL) and pediatric HeH ALLs cluster close to the centromere, suggesting this region to be breakprone, and that five genes on 1q were significantly overexpressed and thus potentially pathogenetically important.
