Leukocyte adhesion deficiency in a female patient without delayed umbilical cord separation.

Leukocyte adhesion deficiency type 1 (LAD-1), a rare disorder of neutrophil function, is classically characterised by delayed umbilical cord separation. We report a case of LAD-1 in a female infant whose umbilical cord separated within 2 weeks of birth and review the literature pertaining to the timing of umbilical cord separation.
