Research Group Genetic Predisposition to Hematologic Disorders. A team led by Michael Doubek, head of the Internal Hematology and Oncology Clinic at Brno University Hospital, is dedicated to identifying genetic predispositions to hematological disorders, particularly rare hereditary blood diseases and malignancies – including variants in genes such as DDX41, RUNX1, GATA2, CEBPA, and others—many of which have a low prevalence (less than 1 in 2,000). Using massively parallel sequencing (MPS) technologies and large-scale genomic projects such as the 1000 Czech Genomes Initiative (A-C-G-T), the team seeks to distinguish pathogenic variants from variants of uncertain significance, assess their functional and phenotypic impact (using approaches such as CRISPR/Cas9), and ultimately integrate these findings into precision medicine to improve the diagnosis, monitoring, and risk assessment of blood disorders.
