Description : Hyper-IgM syndrome is a condition characterized by normal or increased serum IgM concentrations
associated with low or absent serum IgG, IgA, and IgE concentrations, indicating a
defect in the class-switch recombination (CSR) process. For a discussion of genetic
heterogeneity of immunodeficiency with hyper-IgM, see HIGM1 (308230).;
