The workshop will focus on all aspects concerning cancer genetics and cancer cytogenetics in a diagnostic setting. Technical aspects such as conventional karyotyping, methods and principles of fluorescence in situ hybridization (FISH) and new methods in cytogenetics such as micro-array genomic profiling, MLPA and next generation sequencing will be discussed. During the workshop interpretation of cytogenetic and genetic data in relation with cancer (onco-hematology and solid tumors) and predisposition to cancer will be presented. Practical exercises will be offered with the ISCN system for chromosome aberrations. Furthermore students will practice with data obtained by karyotyping, FISH, micro-array and molecular diagnostics and translation of these data in a report. Participants will have the opportunity to present their own observations and cytogenetic findings which are difficult to interpret.
