Abstract

Immunodeficiency-centromeric instability-facial dysmorphism syndrome, characterized by variable immunodeficiency, centromeric instability, and facial anomalies caused by epigenetic dysregulation resulting in hypomethylation, is caused in many patients by mutations in DNMT3B, a DNA methyltransferase gene; associated infections are a major cause of serious sequelae and death. Hematopoietic stem cell transplantation may improve the clinical course in immunodeficiency-centromeric instability-facial dysmorphism syndrome. We report 3 unrelated patients with persistent infections and intestinal complications who successfully underwent hematopoietic stem cell transplantation after nonmyeloablative or myeloablative conditioning regimens using HLA-matched donors. In all cases, donor chimerism led to resolution of intestinal complications and infections, growth improvement, and correction of the immunodeficiency.
