Abstract: | Primary antibody deficiencies (PAD) form the largest group of inherited disorders of the immune system. They are characterized
by a marked reduction or absence of serum immunoglobulins (Ig) due to disturbed B cell differentiation and by a poor response
to vaccination. PAD can be divided into agammaglobulinemia, Ig class switch recombination deficiencies, and idiopathic hypogammaglobulinemia.
Over the past 20 years, defects have been identified in 18 different genes, but in many PAD patients the underlying gene defects
have not been found. Diagnosis of known PAD and discovery of new PAD is important for good patient care. In this review, we
present the effects of genetic defects in the context of normal B cell differentiation, and we discuss how new technical developments
can support understanding and discovering new genetic defects in PAD. |
