The X-linked variant of the Hyper-IgM syndrome. The affected individuals are virtually always male, because males only have one X chromosome, received from their mothers. Their mothers are not symptomatic, even though they are carriers of the allele, because the trait is recessive. Male offspring of these women have a 50% chance of inheriting their mother's mutant allele. [ http://en.wikipedia.org/wiki/Hyper-IgM_syndrome_type_1 ]

This variant of the hyper-IgM syndrome is caused by mutation of the CD40LG gene. The genetic locus for this gene is Xq26. This gene codes for the CD40 ligand, which is expressed on T cells. When the CD40 ligand binds CD40 on B cells, then the B cell switches from producing IgM to producing IgA or IgG.
