Plcg2-Associated Antibody Deficiency And Immune Dysregulation

PLCG2-associated antibody deficiency and immune dysregulation is a rare, hereditary, immune deficiency with skin involvement characterized by early-onset cold urticaria after generalized exposure to cold air or evaporative cooling and not after contact with cold objects. Additional immunologic abnormalities are often present - antibody deficiency, recurrent infections, autoimmune disease and symptomatic allergic disease.
