[Deficient expression of leukocyte adhesion proteins. A new Tunisian case]. / Le défaut d'expression des protéines d'adhésion leucocytaire. A propos d'une nouvelle observation Tunisienne.

Leukocyte adhesion deficiency (LAD) is a rare primary immunodeficiency inherited as an autosomal recessive genetic disorder. LAD was suspected in a four days old girl. She was born from healthy first cousins. A family history of a boy who died from omphalitis and sepsis was reported. Our patient had the severe form, she had delayed umbilical cord separation and suffered recurrent infections. She had a deletion of the G at position 1497. The patient received bone marrow transplantation from her HLA-identical mother at age of 14 months. She is now 9 years old and in good health.
