Hyper IgM syndrome is a rare primary immune deficiency disorders characterized by low or absent levels of serum IgG, IgA, IgE and normal or increased levels of serum IgM. [ 8 ] They are resulting from mutations in the pathway from B-cell activation to isotype class switching.
Immunodeficiency with hyperimmunoglobulin M is a rare disorder characterized by recurrent infections, low or absent IgG, IgE, and IgA levels, and normal or elevated levels of IgM and IgD. [ 2 ] : 84
Different genetic defects cause HIgM syndrome, the vast majority are inherited as an X-linked recessive genetic trait and most with the condition are male. [ 7 ] [ 1 ] [ 2 ] [ 3 ] [ 12 ] [ 4 ] IgM is the form of antibody that all B cells produce initially before they undergo class switching .
Immunoglobulin M (IgM) is the largest of several isotypes of antibodies (also known as immunoglobulin) that are produced by vertebrates. IgM is the first antibody to appear in the response to initial exposure to an antigen ; [ 1 ] [ 2 ] causing it to also be called an acute phase antibody.
