immunodeficiency with hyper-IgM type 5

MIM.608106 12q23-q24.1

Wednesday 26 January 2011

HIGM5 is caused by mutation in the gene encoding uracil-DNA glycosylase (UNG; MIM.191525). HIGM5 is inherited as an autosomal recessive disease.

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.
