Diagnosis of LAD-I was suspected on the basis of clinical features, white blood cell count and absolute neutrophil counts and flow cytometric assessment of expression of CD18 and CD11(a, b, c) on leukocytes. Immunodeficiencies are conditions in which the immune system is not able to protect the body effectively from foreign invaders such as viruses, bacteria, and fungi. It is autosomal recessive and characterized by a mutation in ITGB2, which encodes the common beta-2 subunit of integrin called CD18. Canine leukocyte adhesion deficiency (CLAD) is an inherited blood disorder affecting Irish Setters and German Shepherd Dogs.

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. In leukocyte adhesion deficiency syndrome (LAD), a genetic defect either in [beta]2 integrins (type I) or in fucosylated selectin ligands (type II), leukocytes cannot stop or roll, respectively; this syndrome is characterized by marked leukocytosis and frequent bacterial infections. is a very rare genetic disorder that affects the body's immune system. These adhesion/rolling defects are of three major types: LAD I, LDA II, and LAD III (Figure 60.8).
