Transient hypogammaglobulinemia of infancy
is a form of hypogammaglobulinemia
appearing after birth, leading to a reduction in the level of IgG
, and also sometimes IgA
. (The ratios of immunoglobulins
vary rapidly in all infants, and the term dysgammaglobulinemia
, although theoretically applicable, isn't usually used in this context.)
It can result in increased infections, but it can also present without symptoms.
