Background

Dr. Howard Lederman is a professor of pediatrics at the Johns Hopkins University School of Medicine. He is the director of the Immunodeficiency Clinic, the Pediatric Immunology Laboratory, and the Ataxia-Telangiectasia (A-T) Clinical Center.  

Dr. Lederman specializes in the evaluation, diagnostic testing and long-term management of patients of all ages who have known or suspected primary immunodeficiency diseases. He is an expert on the use of gamma globulin therapy for a wide variety of disorders. 

After receiving his M.D. and Ph.D. from the University of Michigan, Dr. Lederman came to Johns Hopkins Children’s Center for a residency in pediatrics, followed by a fellowship in immunology at the Hospital for Sick Children in Toronto. 

Dr. Lederman’s current research laboratory and clinical research focuses on better understanding and treating patients with ataxia-telangiectasia, a devastating neurological disorder for which there is no cure.

He is a member of numerous professional societies, including American Association of Immunologists, the American Society for Microbiology and the Clinical Immunology Society.
