Sammanfattning : Bacteria have small, streamlined genomes and evolve rapidly. Their large population sizes allow selection to be the main driver of evolution. With advances in sequencing technologies and precise methods for genetic engineering, many bacteria are excellent models for studying elementary questions in evolutionary biology. LÄS MER
Sammanfattning : In recent years, the genetic landscape of B-cell derived lymphoid malignancies, including chronic lymphocytic leukemia (CLL), has been rapidly unraveled, identifying recurrent genetic mutations with potential clinical impact. Interestingly, ~30% of all CLL patients can be assigned to more homogeneous subsets based on the expression of a similar or “stereotyped” B-cell receptor (BcR). LÄS MER
Sammanfattning : Introduction: Haemophilia A (HA) and B (HB) are two of our most common inherited bleeding disorders and are due to a variety of gene mutations. Aims: The overall objective of the present research was to perform clinical and basic scientific studies on haemophilia in Sweden to further improve and individualise the care of haemophilia patients and their relatives.

Sammanfattning : Hereditary factors are thought to play are role in 20-30% of all colorectal cancers Around 6% are found as high penetrant disease-causing mutations in genes correlated to hereditary polyposis or hereditary non-polyposis syndromes. The aim of this thesis was to identify new causative genes and variants and also mutation mechanisms in families presenting a polyposis, atypical polyposis or nonpolyposis CRC phenotype. LÄS MER
Sammanfattning : Comprehensive characterisation of the mutational landscapes of solid tumours is a multistep process involving the collection of suitable samples, the extraction of nucleic acids and the preparation of these materials for mutational analyses. In this thesis, I aimed to develop a streamlined process for the analysis of colorectal cancer (CRC) patient samples in order to identify novel mutations that hallmark the development of advanced disease.
