Primary Immunodeficiency
📋Overview
Primary immunodeficiency (PID) refers to a group of inherited disorders characterized by defects in the immune system, leading to increased susceptibility to infections, autoimmune diseases, and malignancies. These conditions are caused by genetic abnormalities affecting various components of the immune response. The term 'primary immunodeficiency' is preferred over older labels such as 'congenital immunodeficiency' or 'inborn errors of immunity.'
