The research focus of Tommerup Group is mapping of balanced chromosomal rearrangements (BCR) to identify and characterize novel disease and phenotype genes, regulatory domains (Topological Associating Domains (TADs)) of disease genes and novel genetic mechanisms. Characterization of germline chromothripsis and functional studies of non-coding RNA genes. Sex differential responses to Sars-Cov-2-, influenza- and RSV-infections.
