About 70 percent of immunoglobulin deficiencies involve B lymphocytes and 20-30 percent involve T lymphocytes.
Another 10 percent may involve both B and T lymphocytes.
Primary immunoglobulin deficiencies are primarily the result of congenital defects that affect the development and function of B lymphocytes (B cells), the white cells that fight infection and disease.

As the name suggests, killer T lymphocytes act to destroy the target organism.
Congenital immunodeficiencies may occur as a result of defects in B lymphocytes, T lymphocytes, or both.
The congenital immunodeficiency disorder, Bruton's agammaglobulinemia, also known as X-linked agammaglobulinemia, results in a decrease or absence of B lymphocytes and, therefore, a decreased ability to make antibodies.
