CD8α deficiency

CD8 glycoproteins play an important role in maturation and function of MHC class I-restricted T lymphocytes. The disease is transmitted autosomal recessive and it is an immunologic defect characterized by absence of CD8+ cells. Only one deficiency was described until now in a consanguineous family in Spain.
