A Database of Human Hemoglobin Variants and Thalassemias

This is a relational database of information about hemoglobin variants and mutations that cause thalassemia. The initial data came from Syllabi authored by Prof. Titus H.J. Huisman, Mrs. Marianne F.H. Carver, Dr. Erol Baysal, and Prof. Georgi D. Efremov. The HbVar project is an international collaboration. Current curators are George Patrinos at the University of Patras (Greece), Philippe Joly at the Hopital Edouard Herriot in Lyon (France), Henri Wajcman at INSERM Creteil (France), Kamran Moradkhani at the Institute of Biology, Nantes (France), Joseph Borg at the Mater Dei Hospital (Malta), and David Chui at the Boston University Medical Center (USA). Database administration and oversight is by Belinda Giardine and Ross Hardison at The Pennsylvania State University (USA). Visit our query page or summary page to see the types of information available.
