A 13-year-old boy with immunodeficiency with hyper-IgM was analyzed for mutations in the CD40L gene. An insertional mutation of an extra T in a run of four T's was found in the second exon of the gene, leading to a premature translation stop. Genetic counselling of the family was performed, based on mutation detection by PCR/oligohybridization.
