Leukocyte adhesion deficiency-III in an African-American patient.

Leukocyte adhesion deficiency-III (LAD-III) is a rare disorder characterized by abnormal signaling to beta integrins, leading to defective leukocyte adhesion and chemotaxis and platelet aggregation. Here we present the first case of an African-American female infant with this disorder. She had history of multiple infections, bleeding, and leukocytosis since birth. She was successfully treated with allogeneic bone marrow transplant using a reduced intensity-conditioning regimen. Mutations in KINDLIN-3 have been described in LAD-III but the mutations in KINDLIN-3 in her case are unique.
