The workshop will focus on all aspects concerning cancer cytogenetics. 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. Practical exercises will be offered with the ISCN 2013 system for chromosome aberrations and with cytogenetic and genomic databases. Participants will have the opportunity to present their own observations and cytogenetic findings which are difficult to interpret.
