Clinical significance

The IgG1 sub-class accounts for 40 to 80% of total IgG. The relative proportions of the different sub-classes vary with age. Adult concentrations of IgG1 are reached by the age of 2 to 3 years.In adults, IgG1 antibodies tend to be directed at proteinaceous antigens. Children, because of their isotypic immaturity, produce mainly IgG1 antibodies in response to bacteria, be the antigens proteinaceous or polysaccharide-based. Most antibodies directed against viruses are either IgG1 or IgG3.Autoantibodies can be of any of the four sub-classes.
