[[http://www.uniprot.org/uniprot/CD20_HUMAN CD20_HUMAN]] Defects in MS4A1 are the cause of immunodeficiency common variable type 5 (CVID5) [MIM:[http://omim.org/entry/613495 613495]]; also called antibody deficiency due to CD20 defect. CVID5 is a primary immunodeficiency characterized by antibody deficiency, hypogammaglobulinemia, recurrent bacterial infections and an inability to mount an antibody response to antigen. The defect results from a failure of B-cell differentiation and impaired secretion of immunoglobulins; the numbers of circulating B-cells is usually in the normal range, but can be low.<ref>PMID:20038800</ref>
