Sometimes I wish the name weren't so common, but part of me also thinks that one of the reasons it's popular is that it has a very lyrical sound to it. -- ecshell 4/23/2007. This is my name, and I strongly dislike it. I know that it's not always good to have the most common name, but there have only been 3 girls my age that I have ever met with the same name as me. Actually, one of those girls was a year older than me. Anyways. I'd rather have just been named Elisabeth or another L name because I was named after my grandma.
Most hypergammaglobulinemias are caused by an excess of immunoglobulin M (IgM), because this is the default immunoglobulin type prior to class switching. Some types of hypergammaglobulinemia are actually caused by a deficiency in the other major types of immunoglobulins, which are IgA, IgE and IgG. There are 5 types of hypergammaglobulinemias associated with hyper IgM.
1 Anti-convulsants can cause hypogammaglobulinemia or selective IgA deficiency.  Food allergy and other atopic disorders (eg, allergic conjunctivitis, rhinitis, allergic urticaria, atopic dermatitis, asthma) are more common in patients with IgA deficiency than in the general population.
