New genetic immune disorder identified

A new immune disorder has been identified -- DOCK2 deficiency -- named after the mutated gene responsible for the disease. An international team of collaborators studied five children, four boys and one girl, from different ethnic backgrounds who had experienced debilitating infections early in life. The children were diagnosed with combined immunodeficiency, which refers to a group of inherited disorders distinguished by defects in immune system cells called T cells. CIDs also may affect other cells of the immune system, including B cells.
