Leukocyte adhesion deficiency II (LAD II) is characterized by the lack of fucosylated glycoconjugates, including selectin ligands, causing immunodeficiency and severe mental and growth retardation. No deficiency in fucosyltransferase activities or in the activities of enzymes involved in GDP-fucose biosynthesis has been found.
