The Department of Molecular and Clinical Genetics has a broad range of scientific interests. The Department conducts studies on the genetics of cystic fibrosis, primary ciliary dyskinesia and diseases related to genetically determined defects of motile cilia. Department also investigates the molecular and genetic aspects of hematologic diseases (especially acute T-cell lymphoblastic leukemia), as well as monitoring of the treatment response (so called residual disease). Last, but not least, we conduct research on issues related to the genetic diversity of human populations. In all cases, we are interested not only in broadening of the basic knowledge, but also its practical application.
