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 ] IgM is the form of antibody that all B cells produce initially before they undergo class switching due to exposure to a recognized antigen.
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
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.

Intramuscular infusions are no longer widely used, as they can be painful and are more likely to cause reactions. People often experience adverse side effects from immunoglobulin infusions, including: swelling at the insertion site (common in SCIG) chills; headache; nausea (common in IVIG) fatigue (common in IVIG) muscle aches and pain, or ...
Symptoms including blurring or loss of vision, headache, and (rarely) stroke or coma are due to the effects of the IgM paraprotein, which may cause autoimmune phenomena or cryoglobulinemia. Other symptoms of Waldenström macroglobulinemia are due to hyperviscosity syndrome, which is present in 6–20% of patients.

IgM nephropathy or immunoglobulin M nephropathy (IgMN) is a kind of idiopathic glomerulonephritis that is marked by IgM diffuse deposits in the glomerular mesangium. [1] IgM nephropathy was initially documented in 1978 by two separate teams of researchers.
