Mosaicism in X-linked severe combined immunodeficiency.
We performed gamma c gene analysis of a boy with severe combined immunodeficiency whose brother died of the same condition. A base pair deletion in exon 6 was found, which was absent in his mother, indicating maternal mosaicism with important implications for genetic counseling and demonstrating the importance of mutation analysis in boys with severe combined immunodeficiency.
