Hans Rudolf Lytchoff Eiberg

Hans Rudolf Lytchoff Eiberg is an Associate Professor at the Department of Cellular and Molecular Medicine, University of Copenhagen, specializing in Medical Genetics. With a career spanning over 50 years since 1971, he is renowned for discovering that all blue-eyed humans descend from the same common ancestor. His work primarily focuses on genetic research using the Copenhagen Family Bank containing data from 850 families with at least 4 children.

Dr. Eiberg earned his Cand. scient. in Biochemistry from Copenhagen University in Spring 1970, with specialization in Plant Physiology. His professional journey began as an Adjunct at Copenhagen University's Department of Medical Genetics from 1971-1975, progressed to Lecturer and Associate Professor starting in 1975, and evolved into leadership roles as Project Leader of the Family Bank (RC-link) at the Panum Institute since 1980, and Group Leader of the Genome Group/RC-link since 1994.

His research interests encompass genetic and molecular mechanisms underlying inherited disorders and normal traits, with particular focus on eye diseases, skin diseases, psychiatric conditions, and common traits like eye and hair color. He has developed extensive laboratory methods for mapping the human genome, including collection of personal data and blood samples, and established techniques for antibody production, genetic polymorphism analysis, and linkage analysis using specialized software. Dr. Eiberg has explored 22 diseases for chromosomal localization of gene defects, successfully localizing more than 10 diseases for the first time in his laboratory.

His recent publications reveal a strong focus on genetic mapping of various conditions including ulcerative colitis, psychiatric disorders, nephrotic syndrome, movement disorders, microcephaly, cataracts, and migraine. His work bridges classical genetic techniques with modern genomic approaches, maintaining a consistent emphasis on family-based linkage analysis while incorporating newer technologies like HLA typing and RNA analysis.

Among his professional recognitions, Dr. Eiberg received the Silver Medal from Aarhus University in 1972 for his work on band differentiating techniques for human chromosomes. He has served as Vice Chairman of Human Gene Mapping 9 (chromosome 17-19) in Paris 1987 and has been an invited speaker at international conferences in Toronto, Oxford, London, and Verona.

Dr. Eiberg has supervised numerous students including Marie-Louise Bisgaard, Ida Berendt, and µslaug Jon sd¢ttir, and has mentored PhD candidates Søren Eckwald and Yang Huan Ming. His laboratory maintains the Copenhagen Family Bank with extensive biological samples including serum, plasma, erythrocytes from all family members, and B-lymphocytes, DNA, mRNA from 300 families, supporting research on psoriasis, asthma, enuresis, migraine, and other conditions.

As a member of the Human Genome Organization (HUGO), the Danish Society of Medical Genetics, and the European Society of Human Genetics, Dr. Eiberg has contributed significantly to the field through peer review for journals like Human Genetics, Clinical Genetics, and Genomics, while maintaining an active research program that has produced 190 research outputs to date.
