Summaries for CD19 Gene

Entrez Gene Summary for CD19 Gene

  • Lymphocytes proliferate and differentiate in response to various concentrations of different antigens. The ability of the B cell to respond in a specific, yet sensitive manner to the various antigens is achieved with the use of low-affinity antigen receptors. This gene encodes a cell surface molecule which assembles with the antigen receptor of B lymphocytes in order to decrease the threshold for antigen receptor-dependent stimulation. [provided by RefSeq, Jul 2008]

GeneCards Summary for CD19 Gene

CD19 (CD19 Molecule) is a Protein Coding gene. Diseases associated with CD19 include Immunodeficiency, Common Variable, 3 and Common Variable Immunodeficiency. Among its related pathways are Immunoregulatory interactions between a Lymphoid and a non-Lymphoid cell and RET signaling. GO annotations related to this gene include signal transducer activity, downstream of receptor.

  • Immunodeficiency, common variable, 3 (CVID3) [MIM:613493]: 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. {ECO:0000269 PubMed:16672701}. Note=The disease is caused by mutations affecting the gene represented in this entry.
