Recent advances in genetic diagnosis have identified mutations in gene encoding interleukin-10 (IL-10) and IL-10 receptor (IL-10R) proteins as a cause for early-onset enterocolitis leading to hyperinflammatory immune response. Allogeneic HSCT offers a potential cure; however, it was only performed in a few infants and mainly from family-related donors. We report a case of a girl who presented very early in life with severe infantile enterocolitis. Gene sequencing confirmed IL-10R defect. Her older sister died at 13 months of age from severe undiagnosed enterocolitis. There was no family donor. An unrelated search identified a potential 10/10 high-resolution HLA-matched donor. There was some delay in donor activation because IL-10R defect was not on the standard list of indications for unrelated HSCT. Our patient received the unrelated HSCT at seven months of age, and she is currently nine months after transplant and doing very well. Because HSCT is the curative option of choice for this disorder, we encourage adding IL-10 and IL-10R protein defects to the list of HSCT indications for unrelated donor procurement. © 2015 John Wiley & Sons A/S.
