Abstract excerpt
X-linked agammaglobulinemia is caused by mutations in the BTK gene, which result in a precursor B-cell differentiation arrest in the bone marrow and the absence of or strongly reduced B lymphocytes in blood. We identified a patient with a mild clinical phenotype, low numbers of B lymphocytes, and a splice-site mutation in the BTK gene. The precursor B-cell compartment in the bone marrow of this patient was almost...
