Igg deficiency

What is Igg deficiency?

IgG deficiency (Selective deficiency of immunoglobulin G) is a form of dysgammaglobulinemia where the proportional levels of the IgG isotype are reduced relative to other immunoglobulin isotypes. IgG deficiency is often found in children as transient hypogammaglobulinemia of infancy (THI), which may occur with or without additional decreases in IgA or IgM.

IgG has four subclasses: IgG1, IgG2, IgG3, and IgG4. It is possible to have either a global IgG deficiency, or a deficiency of one or more specific subclasses of IgG. The main clinically relevant form of IgG deficiency is IgG2. IgG3 deficiency is not usually encountered without other concomitant immunoglobulin deficiencies, and IgG4 deficiency is very common but usually asymptomatic.
