The American Society of Human Genetics has named Daniel MacArthur as the first recipient of its Early Career Award. He is an assistant professor in the Analytic and Translational Genetics Unit at Massachusetts General Hospital and Harvard Medical School and the co-director of the Medical and Population Genetics Program at the Broad Institute. The new award, which comes with $10,000 in prize money, recognizes contributions of genetics and genomics scientists in the first 10 years of their careers as independent investigators. MacArthur and his colleagues developed the Exome Aggregation Consortium (ExAC) database and website and its successor, the Genome Aggregation Database (gnomAD). He also published many scientific articles on identifying genes associated with rare diseases, in particular muscular disorders.
