Summary

Common variable immunodeficiency-12 with autoimmunity (CVID12) is an autosomal dominant complex immunologic disorder with multisystem involvement. CVID12 is mainly a primary immunodeficiency characterized by recurrent infections and associated with hypogammaglobulinemia. Notably, about half of patients develop autoimmune features, including cytopenia, as well as generalized inflammation and lymphoproliferation manifest as lymphadenopathy or hepatosplenomegaly. A smaller percentage of affected individuals (less than 20%) develop cancer, most commonly solid tumors, including lymphoma. Age at onset and disease severity are highly variable, even within the same family. There is also incomplete penetrance, such that mutation carriers may be asymptomatic, even if they have hypogammaglobulinemia. The gene involved, NFKB1, encodes a transcription factor that regulates the expression of target genes involved in the immune system, thus defining the phenotype as a disorder of immune dysregulation (summary by Fliegauf et al., 2015; Lorenzini et al., 2020). For a general description and a discussion of genetic heterogeneity of common variable immunodeficiency, see CVID1 (607594). [from OMIM]
