Common variable immunodeficiency-10 (CVID10) is an autosomal dominant primary immunodeficiency characterized by childhood-onset of recurrent infections, hypogammaglobulinemia, and decreased numbers of memory and marginal zone B cells. Some patients may develop autoimmune features and have circulating autoantibodies. An unusual feature is central adrenal insufficiency (summary by Chen et al., 2013).

Autosomal recessive primary immunodeficiency with defective spontaneous natural killer cell cytotoxicity- MedGen UID:

- Disease or Syndrome
Immunodeficiency-20 is a rare autosomal recessive primary immunodeficiency characterized by functional deficiency of NK cells. Patient NK cells are defective in spontaneous cell cytotoxicity, but retain antibody-dependent cellular cytotoxicity. Patients typically present early in childhood with severe herpes viral infections, particularly Epstein Barr virus (EBV), and human papillomavirus (HPV) (summary by Grier et al., 2012).
Immunodeficiency 78 with autoimmunity and developmental delay- MedGen UID:
- 1785772
- •Concept ID:
- C5543159
- •
- Disease or Syndrome
Immunodeficiency-78 with autoimmunity and developmental delay (IMD78) is an autosomal recessive systemic disorder characterized by onset of symptoms in early childhood. Affected individuals present with features of immune deficiency, such as recurrent sinopulmonary or skin infections, as well as autoimmunity, including autoimmune cytopenias, hemolytic anemia, and thrombocytopenia. Autoimmune hepatitis or thyroid disease and central nervous system vasculitis with stroke may also occur. There is increased susceptibility to bacterial, viral, and fungal infections. Laboratory studies show lymphopenia with advanced differentiation and premature senescence of CD8+ T cells and B cells; some patients may have hypergammaglobulinemia. The findings indicate immune dysregulation. Patients also have global developmental delay with speech delay and variable intellectual disability. Many patients die prematurely, but successful hematopoietic bone marrow transplant may be curative (summary by Lu et al., 2014 and Atallah et al., 2021).
Immunodeficiency 92- MedGen UID:

- •Concept ID:
- C5562039
- •
- Disease or Syndrome
Immunodeficiency-92 (IMD92) is an autosomal recessive primary immunodeficiency characterized by the onset of recurrent infections in infancy or early childhood. Infectious agents are broad, including bacterial, viral, fungal, and parasitic, including Cryptosporidium and Mycobacteria. Patient lymphocytes show defects in both T- and B-cell proliferation, cytokine secretion, and overall function, and there is also evidence of dysfunction of NK, certain antigen-presenting cells, and myeloid subsets. Hematopoietic stem cell transplantation may be curative (summary by Beaussant-Cohen et al., 2019 and Levy et al., 2021).
