General Discussion
Nezelof syndrome (NS) is an extremely rare immune deficiency disorder in which the cells that normally fight off even common infections do not function properly. Affected individuals are subject to frequent and serious infections. Because neither of the two main infection-fighting cells, T cells and B cells, functions properly, Nezelof syndrome is often referred to as a combined immunodeficiency disorder (CID). Patients with this syndrome usually have small thymus glands in which the cells producing hormones required for development of infection-fighting cells are flawed or malfunctioning.

Nezelof syndrome is usually classified as a T cell deficiency, yet those affected do not have abnormal levels of gammaglobulin, a protein in blood that contains disease-fighting antibodies. T cell dysfunction in the presence of relatively normal concentrations of gammaglobulin is one way of defining Nezelof syndrome. Because there is some immunoglobulin function, NS is never as debilitating as severe combined immunodeficiency (SCID).

Nezelof syndrome is an inherited condition that becomes apparent early in the life of the baby.
