Conditions and Diseases we treat

Primary Immunodeficiencies

The Childhood Primary Immunodeficiency Program at the Maria Fareri Children’s Hospital at Westchester Medical Center and New York Medical College is a multidisciplinary and comprehensive program dedicated to the diagnosis, prevention, treatment and long-term follow up of children diagnosed with primary immunodeficiency syndromes. The program consists of several “state of the art” programs in Newborn Screening, Prevention, Genetic Diagnosis, Stem Cell Transplantation, Reduced Intensity Conditioning and Adoptive Cellular Immunotherapy. The program also provides a unique opportunity for clinical, translational and basic research for students, residents, and fellows focused on the biology and treatment of primary immunodeficiency in children. Most importantly, the program is designed to provide customized and personal care and long-term follow-up to each child with a primary immunodeficiency.


The Primary Immunodeficiency Program is focused on all known immunodeficiencies [Our Clinical Trials, Patient Information], including:

  • Ataxia-Telangiectasia
  • Autoimmune Neutropenia
  • Complement Deficiencies
  • Humoral Immunity
    • Agammaglobulinemia (Bruton’s)
    • Common Variable Immunodeficiency
    • Hyper IgE Syndrome
    • Hyper IgM Syndrome
    • IgA Deficiencies
    • IgM Deficiency
    • Severe Combined Immune Deficiency (SCID)
  • Neutropenia
    • Congenital Neutropenia
    • Cyclic Neutropenia
