General Discussion

Leukocyte adhesions deficiency (LAD) syndromes are a group of rare disorders affecting the immune system. LAD syndromes are characterized by defects affecting how white blood cells (leukocytes) respond and travel to the site of a wound or infection. Three distinct types of leukocyte adhesion syndrome have been identified. The specific symptoms and the severity of LAD syndromes vary from one person to another. All affected individuals develop an increased susceptibility to developing recurrent bacterial and fungal infections. Additional symptoms may occur depending upon the specific subtype present. LAD syndromes are caused by mutations of specific genes that contain instructions for creating certain proteins that are necessary for white blood cells to travel from the bloodstream to the site of an infection or inflammation. Individuals with severe forms of LAD may have near complete absence of these proteins. Individuals who have milder forms of LAD syndromes have deficient levels of these proteins, but retain some residual protein activity.
